A command to find out what the day ends in. Can be edited slightly to find out what "any" output ends in. NB: I haven't tested with weird and wonderful output. Show Sample Output
I created this command to give me a quick overview of how many file types a directory, and all its subdirectories, contains. It works based off file extension, rather than file(1)'s magic output, because it ended up being more accurate and less confusing. Files that don't have an ext (README) are generally not important for me to want to count, but you're free to customize this fit your needs. Show Sample Output
find -exec is evil since it launches a process for each file. You get the total as a bonus. Also, without -n sort will sort by lexical order (that is 9 after 10).
If you use HISTTIMEFORMAT environment e.g. timestamping typed commands, $(echo "1 2 $HISTTIMEFORMAT" | wc -w) gives the number of columns that containing non-command parts per lines. It should universify this command. Show Sample Output
Find the source file which contains most number of lines in your workspace :) Show Sample Output
command was too long... this is the complete command: fname=$1; f=$( ls -la $fname ); if [ -n "$f" ]; then fsz=$( echo $f | awk '{ print $5 }' ); if [ "$fsz" -ne "0" ]; then nrrec=$( wc -l $fname | awk '{ print $1 }' ); recsz=$( expr $fsz / $nrrec ); echo "$recsz"; else echo "0"; fi else echo "file $fname does not exist" >&2; fi First the input is stored in var $fname The file is checked for existance using "ls -lart". If the output of "ls -lart" is empty, the error message is given on stderr Otherwise the filelength is taken from the output of "ls -lart" (5th field) With "wc -l" the number of records (or lines) is taken. The record size is filelength devided by the number of records. please note: this method does not take into account any headers, variable length records and only works on ascii files where the records are sperated by 0x0A (or 0x0A/0x0D on MS-DOS/Windows).

Use bc for decimals...
Kills all process that belongs to the user that runs it - excluding bash, sshd (so putty/ssh session will be spared). The bit that says grep -vE "..." can be extended to include ps line patterns that you want to spare. If no process can be found on the hitlist, it will print # NOTHING TO KILL. Otherwise, it will print # KILL EM ALL, with the cull list.

Enhancement for the 'busy' command originally posted by busybee : less chars, no escape issue, and most important it exclude small files ( opening a 5 lines file isn't that persuasive I think ;) ) This makes an alias for a command named 'busy'. The 'busy' command opens a random file in /usr/include to a random line with vim.

You need: pxz for the actual work (http://jnovy.fedorapeople.org/pxz/). The function could be better with better multifile and stdin/out support.
