This shell function uses curl(1) as it is more portable than wget(1) across Unices, to show what site a shortened URL is pointing to, even if there are many nested shortened URLs. It is a refinement to www.commandlinefu.com/commands/view/9515/expand-shortened-urls to make it better for use in scripts. Only displays final result.

List all files in a directory in reverse order by modified timestamp. When piped through tail the user will see the most recent file name.

lastfile () { find ${1:-.} -maxdepth 1 -type f -printf "%T+ %p\n" | sort -n | tail -n1 | sed 's/[^[:space:]]\+ //'; }

new way to replace text file with dd,faster than head,sed,awk if you do this with big file

wget -qO - --post-data "data[Row][cripted]=1cb251ec0d568de6a929b520c4aed8d1" http://md5-decrypter.com/ | grep -A1 "Decrypted text" | tail -n1 | cut -d '"' -f3 | sed 's/>//g; s/<\/b//g'

Decrypt MD5 , replace 1cb251ec0d568de6a929b520c4aed8d1 with the MD5 string you want to decrypt

Tail is much faster than sed, awk because it doesn't check for regular expressions.

Maybe very limited in its applicability but could be of use at times.

say only processes a complete file, at eof, so following a file isn't possible. Quick and dirty perl oneliner to feed each line from the tail -f to say. Yes, expensive to lauch a new process each line.

This little ditty was prompted by a discussion on how horrible it is to use VoiceOver on ncurses programs such as irssi.

Sort by time and Reverse to get Ascending order, then display a marker next to the a file, negate directory and select only 1 result

Not perfect but working (at least on the project i wrote it ;) )

Specify what you want search in var search, then it grep the folder and show one result at a time.

Press enter and then it will show the next result.

It can work bad on result in the firsts lines, and it can be improved to allow to come back.

But in my case (a large project, i was checking if a value wasn't used withouth is corresponding const and the value is "1000" so there was a lot of result ...) it was perfect ;)

Replace the head -1 with head -n that is the n-th item you want to go to.

Replace the head with tail, go to the last dir you listed.

You also can change the parameters of ls.

netstat -an |grep ":80" |awk '{print $5}' | sed s/::ffff://g | cut -d: -f1 |sort |uniq -c |sort -n | tail -1000 | grep -v "0.0.0.0"

It willl popup a message for each new entry in /var/log/messages

found on the notify-send howto page on ubuntuforums.org.

Posted here only because it is one of the favourites of mine.
