  • It starts in the current working directory. It removes the empty directory and its ancestors (unless the ancestor contains other elements than the empty directory itself). It will print a failure message for every directory that isn't empty. This command handles correctly directory names containing single or double quotes, spaces or newlines. If you do not want only to remove all the ancestors, just use: find . -empty -type d -print0 | xargs -0 rmdir

Check These Out

Save an HTML page, and covert it to a .pdf file
Uses htmldoc to perform the conversion

finds the c files with lines containing 'mcs', in the folders under the current folder

Jump to a directory, execute a command and jump back to current dir

du command without showing other mounted file systems

list files recursively by size

send substituted text to a command without echo, pipe
zsh only - This avoids the need for echo "message" | which creates an entire subshell. Also, the text you are most likely to edit is at the very end of the line, which, in my opinion, makes it slightly easier to edit.

aptbackup restore
Use when aptbackup will not start or you just want to see what's going on.

Rename files in batch

df without line wrap on long FS name
-P uses the POSIX output format, which makes information on each file system always printed on exactly one line. "column -t" makes a table from the input.

copies 20 most recently downloaded mp3 files (such as from Miro) into a directory
Change ~/tmp to the destination directory, such as your mounted media. Change -n20 to whatever number of files to copy. It should quit when media is full. I use this to put my most recently downloaded podcasts onto my phone.
