  • I don't know if you've used sqsh before. But it has a handy feature that allows you to switch into vim to complete editing of whatever complicated SQL statement you are trying to run. But I got to thinking -- why doesn't bash have that? Well, it does. It's called '|'! Jk. Seriously, I'm pretty sure this flow of commands will revolutionize how I administer files. And b/c everything is a file on *nx based distros, well, it's handy. First, if your ls is aliased to ls --color=auto, then create another alias in your .bashrc: alias lsp='ls --color=none' Now, let's say you want to rename all files that begin with the prefix 'ras' to files that begin with a 'raster' prefix. You could do it with some bash substitution. But who remembers that? I remember vim macros because I can remember to press 'qa' and how to move around in vim. Plus, it's more incremental. You can check things along the way. That is the secret to development and probably the universe. So type something like: lsp | grep ras Are those all the files you need to move? If not, modify and re-grep. If so, pipe it to vim. lsp | grep ras | vim - Now run your vim macros to modify the first line. Assuming you use 'w' and 'b' to move around, etc., it should work for all lines. Hold down '@@', etc., until your list of files has been modified from ras_a.h ras_a.cpp ras_b.h ras_b.cpp to: mv ras_a.h raster_a.h mv ras_a.cpp raster_a.cpp mv ras_b.h raster_b.h mv ras_b.h raster_b.cpp then run :%!bash then run :q! then be like, whaaaaa? as you realize your workflow got a little more continuous. maybe. YMMV.

  • This script creates date based backups of the files. It copies the files to the same place the original ones are but with an additional extension that is the timestamp of the copy on the following format: YearMonthDay-HourMinuteSecond Show Sample Output

  • This script will list all the files in the tarballs present on any folder or subfolder of the provided path. The while loop is for echoing the file name of the tarball before listing the files, so the tarball can be identified


    -2
    find <path> -name "*.tgz" -or -name "*.tar.gz" | while read file; do echo "$file: "; tar -tzf $file; done

  • This command will copy a folder tree (keeping the parent folders) through ssh. It will: - compress the data - stream the compressed data through ssh - decompress the data on the local folder This command will take no additional space on the host machine (no need to create compressed tar files, transfer it and then delete it on the host). There is some situations (like mirroring a remote machine) where you simply cant wait for a huge time taking scp command or cant compress the data to a tarball on the host because of file system space limitation, so this command can do the job quite well. This command performs very well mainly when a lot of data is involved in the process. If you copying a low amount of data, use scp instead (easier to type) Show Sample Output

  • Strips comments from at least bash and php scripts. Normal # and // as well as php block comments removes all of the: empty/blank lines lines beginning with # lines beginning with // lines beginning with /* lines beginning with a space and then * lines beginning with */ It also deletes the lines if there's whitespace before any of the above. Add an alias to use in .bashrc like this: alias stripcomments="sed -e '/^[[:blank:]]*#/d; s/[[:blank:]][[:blank:]]*#.*//' -e '/^$/d' -e '/^\/\/.*/d' -e '/^\/\*/d;/^ \* /d;/^ \*\//d'"

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

On Screen micro display for battery and CPU temperature. nifty, small, omnipresent
My firefox overheats my cpu, sometimes above 90 degrees Celsius ( hence the name? ) To keep an eye on temperature, I put this command inside KAlarm ( a kind of cron) to be repeated every minute, for 5 seconds, color red ( default for osd_cat). Its pretty, ultra small, displays a micro 2 lines text on every desktop and over everything and do not steal focus or interrupt any task. I get the information passively, in the low profile bottom of the screen. Of course you can use it inside a terminal. Just do it: watch -n 60 'acpi -t | osd_cat -p bottom'

Find files and calculate size of result in shell
Using find's internal stat to get the file size is about 50 times faster than using -exec stat.

Print IP of any interface. Useful for scripts.

Get the size of all the directories in current directory

Search and Replace across multiple files
- grep for the word in a files, use recursion (to find files in sub directories), and list only file matches -| xargs passes the results from the grep command to sed -sed -i uses a regular expression (regex) to evaluate the change: s (search) / search word / target word / g (global replace)

Write comments to your history.
A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.

Retrieve the size of a file on a server
- Where $URL is the URL of the file. - Replace the $2 by $3 at the end to get a human-readable size. Credits to svanberg @ ArchLinux forums for original idea. Edit: Replaced command with better version by FRUiT. (removed unnecessary grep)

Set laptop display brightness
Run as root. Path may vary depending on laptop model and video card (this was tested on an Acer laptop with ATI HD3200 video). $ cat /proc/acpi/video/VGA/LCD/brightness to discover the possible values for your display.

find files containing text
I find this format easier to read if your going through lots of files. This way you can open the file in any editor and easily review the file

Show numerical values for each of the 256 colors in ZSH
This will show a numerical value for each of the 256 colors in ZSH. Everything in the command is a ZSH builtin, so it should run on any platform where ZSH is installed. Prints one color per line. If someone is interested in formatting the output, paste the alternative.
