Speed up the keyboard repeat rate in X server

Rename files in batch

Show when filesystem was created

Show apps that use internet connection at the moment.
show only the name of the apps that are using internet

Load all files (including in subdirs), whose name matches a substring, into Vim
This command searches the current directory, and all of its subdirs, for files that have the string "foo" in their filename (foo.c, two-foo.txt, index-FOO-bar.php, etc), and opens them in Vim. It ignores any hidden .svn directories. Change -iname to -name if you want to do case-sensitive matches. Files open in buffers by default, so to verify that the correct files were opened, type ":list". You can load all the files in tabs by doing ":tab ball" or use 'vim -p' on the command-line to load files straight to tabs. If you get permission denied errors, do: vim $(find . ! -path \*.svn\* -type -f iname \*foo\* 2>/dev/null) To narrow it down to a single file extension, such as .php files, use \*foo\*.php (or '*foo*.php'. Which ever you prefer)

Print current running shell, PID
works as well as echo $0, but also prints process id, which pts you're using. echo $SHELL doesn't always get updated when changing shells, so this is a better solution than that. Just one more variation on a theme.

Get the current svn branch/tag (Good for PS1/PROMPT_COMMAND cases)
uses just one sed

Convert seconds to [DD:][HH:]MM:SS
Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

check open ports without netstat or lsof
