It tries to identify the file types in a directory and adds or replaces them with their appropriate extensions. Please, update the "file" tool before use it (last version: 5.37): https://github.com/file/file

It happened to me that I got a season of a tv-show which had all files under the same folder like /home/blah/tv_show/season1/file{1,2,3,4,5,...}.avi But I like to have them like this: /home/blah/tv_show/season1/e{1,2,3,4,5,...}/file{1,2,3,4,5,...}.avi So I can have both the srt and the avi on one folder without cluttering much. This command organizes everything assuming that the filename contains Exx where xx is the number of the episode. You may need to set:
IFS=$'\n'if your filenames have spaces.-1season=1; for file in $(ls) ; do dir=$(echo $file | sed 's/.*S0$season\(E[0-9]\{2\}\).*/\1/'); mkdir $dir ; mv $file $dir; done -
Next time you see a mac fanboy bragging about 64-bitness of 10.6 give him this so he might sh? Show Sample Output

lists the files found by find, waits for user input then uses xdg-open to open the selected file with the appropriate program. usage: findopen path expression [command] With the third optional input you can specify a command to use other than xdg-open, for example you could echo the filename to stdout then pipe it to another command. To get it to work for files with spaces it gets a bit messier...
findopen() { files=( $(find "$1" -iname "$2" | tr ' ' '@') ); select file in "${files[@]//@/ }"; do ${3:-xdg-open} "$file"; break; done }You can replace the @ with any character that probably wont be in a file name.-1findopen() { local PS3="select file: "; select file in $(find "$1" -iname "$2"); do ${3:-xdg-open} $file; break; done } -

This takes quite a while on my system. You may want to test it out with /bin first, or background it and keep working. If you want to get rid of the "No manual entry for [whatever]" and just have the [whatever], use the following sed command after this one finishes.
sed -n 's/^No manual entry for \(.*\)/\1/p' nomanlist.txtShow Sample Output-2for file in $(ls /usr/bin ) ; do man -w $file 2>> nomanlist.txt >/dev/null ; done -
This heavy one liner gets all the files in the "/music/dir/" directory and filters for non 44.1 mp3 files. After doing this it passes the names to sox in-order to re-sample those files. The original files are left just in case.
-2file /music/dir/* | grep -v 44.1 | sed 's/:.*//g' | grep .mp3 | { while IFS= read; do filebak="\"$REPLY.original\""; file="\"$REPLY\""; mv $file $filebak; sox -t mp3 $filebak $file rate 44k; done; }; - ‹ First < 4 5 6 7 >
