Install pip with Proxy

Display list of available printers

add all files not under version control to repository

checks which files are not under version control, fetches the names and runs them through "svn add". WARNING: doesn't work with white spaces.

find filenames and directory names that doesn't conform ISO 9660 level 2

You might want to check what file and directory names would be renamed or chopped if you create iso 9660 level 2 image out of them. Use this command to check first.

sleep until X o'clock

pauses exactly long enough to wake at the top of the hour

List the Sizes of Folders and Directories

I wanted an easy way to list out the sizes of directories and all of the contents of those directories recursively.

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" }

move you up one directory quickly

In bash, this turns on auto cd. If a command is just a directory name, it cd's into that directory.

Do a search-and-replace in a file after making a backup
