Like symlinked directories, you can mount a directory at a different location. For example mounting a directory from one location in to the http root without having to make your program follow symlinks or change permissions when reading.

(Debian/Ubuntu) Discover what package a file belongs to

'dpkg -S' just matches the string you supply it, so just using 'ls' as an argument matches any file from any package that has 'ls' anywhere in the filename. So usually it's a good idea to use an absolute path. You can see in the second example that 12 thousand files that are known to dpkg match the bare string 'ls'.

A faster ls

Sometimes "ls" is just too slow, especially if you're having problems with terminal scroll speed, or if you're a speed freak. In these situations, do an echo * in the current directory to immediately see the directory listing. Do an echo * | tr ' ' '\n' if you want a column. Do an alias ls='echo *' if you want to achieve higher echelons of speed and wonder. Note that echo * is also useful on systems that are so low in memory that "ls" itself is failing - perhaps due to a memory leak that you're trying to debug.

IP address of current host

I've seen some versions of hostname that don't have the -i option, so this may not work everywhere. When available, it's a better alternative than using ifconfig and wasting eyeball muscle to search for the address, and it's definitely simpler than using awk/sed.

Record output of any command using 'tee' at backend; mainly can be used to capture the output of ssh from client side while connecting to a server.

Optionally, you can create a new function to do this with a custom command. Edit $HOME/.bashrc and add:

myssh () { ssh $1 | tee sshlog ; }

Save it.

At command prompt:

myssh [email protected]

Add 10 random unrated songs to xmms2 playlist

If you're like me and want to keep all your music rated, and you use xmms2, you might like this command.

I takes 10 random songs from your xmms2 library that don't have any rating, and adds them to your current playlist. You can then rate them in another xmms2 client that supports rating (I like kuechenstation).

I'm pretty sure there's a better way to do the grep ... | sed ... part, probably with awk, but I don't know awk, so I'd welcome any suggestions.

Output a list of svn repository entities to xml file

I use this to pull the last commit date for everything in my repo, so I can tell the client which files haven't been touched or updated since the repo was created. Another way to do it is to use svn log, but that does not pull the "kind" attribute. It does, however, give you the commit message. Both are very useful.

Sometimes you need to use a port that is already opened by some program , and you don't know who to "kill" for it to release - so, now you do !

/^/R addfile -- says for every line that matches "has a start of line" output a line from the file addfile.

> savefile (optional) -- redirect output to savefile file.
