Remove a line from a file using sed (useful for updating known SSH server keys when they change)

Easily removes line #2 in ~/.ssh/known_hosts.

List OSX applications and versions.

Uses find, plutil and xpath.

Note: Some applications don't have proper information. system_profiler might be better to use.

It's a bit slow query.

Due to command length limit, I removed -name "*.app" and CFBundleName.

Functions: cat diff ssh

Compare a remote file with a local file

Or, if you have restricted access for sftp only, I think you can still do this:

diff /path/to/localfile <(scp [email protected]:/path/to/remotefile >(cat))

while series of video and subtitles have unmatched file names, rename subtitles the same as video files.

Subtitles' file names contain S04E01, S04E02, ... S04E12 and end with ".smi".

Videos' file names contain S04E01, S04E02, ... S04E12 and end with ".avi".

You can change the patterns by changing `ls *S04E$jj*.smi` and `ls *S04E$jj*.avi` parts.

You can change the number of starting and ending file by changing `seq -f "%02.0f" 1 12` part.

Avoid using seq and pad numbers with leading zeros

zsh only

I always hated resorting to using $(seq -w 1 99) to pad numbers. zsh provides a shortcut that couldn't be more intuitive. It also works in reverse {99..01}

Find artist and title of a music cd, UPC code given (first result only)

Substitute that 724349691704 with an UPC of a CD you have at hand, and (hopefully) this oneliner should return the $Artist - $Title, querying discogs.com.

Yes, I know, all that head/tail/grep crap can be improved with a single sed command, feel free to send "patches" :D

Enjoy!
