uses the previous "chr" function and uses it to create the inverse function "ord" by brute force.
It's slow, It's inelegant, but it works.
I thought I needed ord/chr to do a cartesian cipher in shell script a whie ago, but eventualy I realized I could get fancy with tr and do the same thing...
Calculates the size on disk for each package installed on the filesystem (or removed but not purged). This is missing the
| sort -rn
which would put the biggest packges on top. That was purposely left out as the command is slightly on the slow side
Also you may need to run this as root as some files can only be checked by du if you can read them ;)
After this, just type:
You need to install "beep" before this would make the beep sound.
Save it in your .profile if you want to use it later
WARNING: this command won't exit until it is successful. You won't be able to CONTROL+C out of it.
I find the ouput of ls -lR to be un-satisfying (why is the path data up there?) and find syntax to be awkward. Running 'du -a' means you will have likely to trim-off filesize data before feeding filenames to the next step in the pipe.
This command dumps all SVN repositories inside of folder "repMainPath" (not recursively) to the folder "dumpPath", where one dump file will be created for each SVN repository.
Same thing, only "head" instead of grep/egrep..
search argument in PATH
accept grep expressions
without args, list all binaries found in PATH
Rainbow, instead of greys
Based on the MrMerry one, just add some visuals to differentiate files and directories
Based on the MrMerry one, just add some visuals and sort directory and files
The important thing to note in this command, is the "-n" flag.
Compile *.c files with "gcc -Wall" in actual directory, using as output file the file name without extension.
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.
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.
Sqlite database keeps collecting cruft as time passes, which can be cleaned by the 'vacuum;' command. This command cleans up the cruft in all sqlite files relating to the user you have logged in as. This command has to be run when firefox is not running, or it will exit displaying the pid of the firefox running.
Renames all the jpg files as their timestamps with ".jpg" extension.
Find Word docs by filename in the current directory, convert each of them to plain text using antiword (taking care of spaces in filenames), then grep for a search term in the particular file.
(Of course, it's better to save your data as plain text to make for easier grepping, but that's not always possible.)
Requires antiword. Or you can modify it to use catdoc instead.
Same as above but slooooow it down
In Debian based distros, this command will list 'binutils' package details which contains 'nm' command. You can replace 'nm' to any other command.
Found this one little more for me. This one removes the perl dependency (from command 2535).

Obviously, you can replace 'man' command with any command in this command line to do useful things. I just want to mention that there is a way to list all the commands which you can execute directly without giving fullpath.
Normally all important commands will be placed in your PATH directories. This commandline uses that variable to get commands. Works in Ubuntu, will work in all 'manpage' configured *nix systems.
