When you run a lot of containers the built in docker ps output becomes unreadable. This command formats the output to be easier on the eyes. Requires q (https://github.com/harelba/q) text as data. Show Sample Output

This is a specialized command for Ericsson CS5.2 - Getting the test case trace on SDP

This command allows to follow up a trace on SDP (CS5.2), at the same time as the trace records are stored in the file with "raw" format. Trace files in native format are useful to filter the records before to translation from '|' to '\n'. Example: grep -v OP_GET <raw-records>.trace | tr '|' '\n' Show Sample Output

tail -1f /var/opt/fds/logs/TraceEventLogFile.txt.0 | grep <msisdn> | tee <test-case-id>.trace | tr '|' '\n'

Numerically sorted human readable disk usage

This approach deals with special characters such as apostrophe and whitespace in the file/directory names. tr '\n' '\0' converts the newline delimiting into NUL delimitering which xargs -0 expects. It works on systems which do not yet support xargs -d or sort -h, and includes files in addition to directories. Show Sample Output

nmap scan hosts for IP, MAC Address and device Vendor/Manufacturer

In the field, I needed to script a process to scan a specific vendor devices in the network. With the help of nmap, I got all the devices of that particular vendor, and started a scripted netcat session to download configuration files from a tftp server. This is the nmap loop (part of the script). You can however, add another pipe with grep to filter the vendor/manufacturer devices only. If want to check the whole script, check in http://pastebin.com/ju7h4Xf4 Show Sample Output

Recursively remove directories less than specified size

Removes directories which are less than 1028KB total. This works for systems where blank directories are 4KB. If a directory contains 1 MB (1024KB) or less, it will remove the directory using a path relative to the directory where the command was initially executed (safer than some other options I found). Adjust the 1028 value for your needs. It would be helpful to test the results before proceeding with the removal. Simply run all but the last two commands to see a list of what will be removed: du | awk '{if($1<1028)print;}' | cut -d $'\t' -f 2- If you're unsure what size a blank folder is, test it like this: mkdir test; du test; rmdir test

remove accents from file name

I had trouble with accent I could do a simple mv by hand but it is not efficient. I found this online http://www.unix.com/shell-programming-and-scripting/158635-remove-spanish-accent-file-name.html but I could not specify the accented letter direcly because it is not in the same encoding as my cli so I changed the char for their octal value. to add accent I use this table http://linux.about.com/library/cmd/blcmdl7_iso_8859-1.htm and add the values to the tr part. the other "duplicates" where not working for me. comment to help me better this script. :) Show Sample Output

yet another random password generator.

this one includes special characters. note some some chars may be disallowed on windows systems. *nix will allow pretty much any character in a password except a carriage return. you do not want non printing characters in your password, so this is limited to the printable chars displayed on a keyboard , less space and return. edited to fix minor typo Show Sample Output

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.

Load all files (including in subdirs), whose name matches a substring, into Vim

This command searches the current directory, and all of its subdirs, for files that have the string "foo" in their filename (foo.c, two-foo.txt, index-FOO-bar.php, etc), and opens them in Vim. It ignores any hidden .svn directories. Change -iname to -name if you want to do case-sensitive matches. Files open in buffers by default, so to verify that the correct files were opened, type ":list". You can load all the files in tabs by doing ":tab ball" or use 'vim -p' on the command-line to load files straight to tabs. If you get permission denied errors, do: vim $(find . ! -path \*.svn\* -type -f iname \*foo\* 2>/dev/null) To narrow it down to a single file extension, such as .php files, use \*foo\*.php (or '*foo*.php'. Which ever you prefer)

Download Youtube Playlist

This will download a Youtube playlist and mostly anything http://code.google.com/apis/youtube/2.0/reference.html#Video_Feeds The files will be saved by $id.flv

backup with mysqldump a really big mysql database to a remote machine over ssh

backup big mysql db to remote machine over ssh. "--skip-opt" option is needed when you can?t allocate full database in ram.

Disable sending of start/stop characters

This command disable sending of start/stop characters. It's useful when you want to use incremental reverse history search forward shortcut (Ctrl+s). To enable again, type: $ stty -ixoff

Search some text from all files inside a directory

ARP Scan

A much quicker and (not dirtier) option. use the man page for help. On linux/ubuntu you will need to `sudo apt-get -y install arp-scan`.

Backup a file with a date-time stamp

Appends the input file with the date format YYYY-MM-DD.bak. Also runs silently if you remove the -v on the cp at the end of the function.

list files recursively by size

Remove all .svn folders

With the plus instead of semicolon, find builds the (eg.) rm command like xargs does - invokes as few extra processes as possible.
