Instead of tedious manual mv commands and tabbing, this routine creates a file listing all the filenames in the PWD twice, edit the second instance on each line to the new name, then save the file, the routine does the rest. Feel free to replace nano with your holy war editor of choice.

You will get a lot of "mv: 'x' and 'x' are the same file" warnings, these could be cleaned up but the routine works.

function titlescroll { _X=0 _TITLEMSG=$1 _WIDTH=${2:-16} _TITLEMSG=`printf "%$((${#_TITLEMSG}+$_WIDTH))s" "$_TITLEMSG"` while `true` do _X=$(((_X+1)%${#_TITLEMSG})) xtitle "${_TITLEMSG:_X:_WIDTH}" done }

titlescroll "message" <width>

Requires command "xtitle" or replace with:

echo -ne "\e]0;TEXT_HERE\007"
getent passwd|cut -d: -f1|xargs -n1 passwd -e

User: romulusnr
Functions: cut getent passwd xargs

Alternately for those without getent or only want to work on local users it's even easier:

cut -d: -f1 /etc/passwd|xargs -n1 passwd -e

Note that not all implementations of passwd support -e. On RH it would be passwd -x0 (?) and on Solaris it would be passwd -f.

netstat -an|grep -ci "tcp.*established"
2009-10-09 01:08:18
User: romulusnr
Functions: grep netstat

If you want prepend/append text just wrap in echo:

echo Connected: `netstat -an|grep -ci "tcp.*established"`
ls -F|grep /

User: romulusnr
Functions: grep ls

No need for -l and the output can be sent directly into another function expecting directory names.

_llines=100; while [ $_llines -gt 1 ]; do echo $_llines; _llines=$(($_llines-1)); done

You've opened a terminal window and you've connected off to a remote host that didn't pick up your terminal size, and all your curses and paging apps are screwed up as a result. You need to quickly determine how many lines are in your current terminal view (to feed into "stty rows X").
