Simple command to convert a large number of images into jpeg-format. Will delete originals after conversion.

OSX's BSD version of the du command uses the -d argument instead of --max-depth.

Use `zless` to read the content of your *rss.gz file:

jhead is a very nice tool to do all sorts of things with photographs, in a batch-oriented way. It has a specific function to rename files based on dates, and the format I used above was just an example.

ls -1 *.jpg | while read fn; do export pa=`exiv2 "$fn" | grep timestamp | awk '{ print $4 " " $5 ".jpg"}' | tr ":" "-"`; mv "$fn" "$pa"; done

Renames all the jpg files as their timestamps with ".jpg" extension.

In Bash, when defining an alias, one usually loses the completion related to the function used in that alias (that completion is usually defined in /etc/bash_completion using the complete builtin).

It's easy to reuse the work done for that completion in order to have smart completion for our alias.

That's what is done by this command line (that's only an example but it may be very easy to reuse).

Note 1 : You can use given command line in a loop "for old in apt-get apt-cache" if you want to define aliases like that for many commands.

Note 2 : You can put the output of the command directly in your .bashrc file (after the ". /etc/bash_completion") to always have the alias and its completion

since fuse mounts do not appear in /etc/mtab (fuse can't write there, dunno if it would if it could) this is propably a better way.

Nothing fancy it just converts one file from one character encoding into another one.

Remove newlines from output.

One character shorter than awk /./ filename and doesn't use a superfluous cat.

To be fair though, I'm pretty sure fraktil was thinking being able to nuke newlines from any command is much more useful than just from one file.

Lets you set all the java alternatives at once to a matching version. Also has options for just changing the jre or the plugin.

?Cat and grep? You can use only grep ("grep \. filename"). Better option is awk.

cat filename | grep .
