See non printable caracters like tabulations, CRLF, LF line terminators ( colored )

For fancier and cleaner output, try the following snippet :

showendlines(){ while read i; do od --address-radix=n --width=$(wc -c <<< "$i") -c <<< "$i" | perl -pe 's/.\K\s{2,3}//g'; done < $1 | grep --color '\\.'; }

Now you can run that with :

showendlines <FILE>

Extract all urls from the last firefox sessionstore.js file used.

Require "grep -P" ( pcre ).

If you don't have grep -P, use that :

grep -Eo '"url":"[^"]+' $(ls -t ~/.mozilla/firefox/*/sessionstore.js | sed q) | cut -d'"' -f4

Know when you will type :q in your term instead of vi(m), the alias will chewed you out.

For vi(m) users :

Add it in your ~/.bashrc

Add an "exit" @ the end if you are masochist ;)

Show local/public IP adresses with or without interface argument using a shell function for Linux and MacOsX

Like the tiltle said, you can use an argument too ( the interface )

MyIps eth0

will show only the IP of this interface and the public IP

( tested with Linux )

You can add that function in ~/.bashrc, then

. ~/.bashrc

Now you are ready to call this function in all your terms...

straceprocessname(){ x=( $(pgrep "$@") ); [[ ${x[@]} ]] || return 1; strace -vf ${x[@]/#/-p }; }

Strace all signals processes based on a name ( The processes already started... ) with bash built-in

Especially for sysadmins when they don't want to waste time to add -p flag on the N processes of a processname.

In the old school, you did ;

pgrep processname

and typing strace -f -p 456 -p 678 -p 974...

You can add -f argument to the function. That way, the function will deal with pgrep to match the command-line.

Example :

processname -f jrockit

Short Information about loaded kernel modules

I modify 4077 and marssi commandline to simplify it and skip an error when parsing the first line of lsmod (4077). Also, it's more concise and small now. I skip using xargs ( not required here ). This is only for GNU sed.

For thoses without GNU sed, use that :

modinfo $(lsmod | awk 'NR>1 {print $1}') | sed -e '/^dep/s/$/\n/g' -e '/^file/b' -e '/^desc/b' -e '/^dep/b' -e d

Display or use a random file from current directory via a small bash one-liner

An other way to run it ( playing a random file ending with avi, flv or mpeg ) from a specified dir and a specified type of extension :

making MOVIE array with a glob :

MOVIE=( /PATH/TO/MY/FAVORITE/MOVIES/*.{avi,flv,mpeg} )

playing the random file from a random key from the array

mplayer ${MOVIE[ RANDOM % ( ${#i[@]} + 1 ) ]]}

I use only globs and a bash array.

I use GNU bash, version 3.2.48
