Unaccent an entire directory tree with files.

This command changes all filename and directories within a directory tree to unaccented ones. I had to do this to 'sanitize' some samba-exported trees. The reason it works might seem a little difficult to see at first - it first reverses-sort by pathname length, then it renames only the basename of the path. This way it'll always go in the right order to rename everything.

Some notes:

1. You'll have to have the 'unaccent' command. On Ubuntu, just aptitude install unaccent.

2. In this case, the encoding of the tree was UTF-8 - but you might be using another one, just adjust the command to your encoding.

3. The program might spit a few harmless errors saying the files are the same - not to fear.

Functions: awk ps

Search for an active process without catching the search-process

This does the same thing as many of the 'grep' based alternatives but allows a more finite control over the output. For example if you only wanted the process ID you could change the command:

ps -ef | awk '/mingetty/ && !/awk/ {print $2}'

If you wanted to kill the returned PID's:

ps -ef | awk '/mingetty/ && !/awk/ {print $2}' | xargs -i kill {}
