Create a Multi-Part Archive Without Proprietary Junkware

Leave it to a proprietary software vendor to turn a cheap and easy parlor trick into a selling point. "Hey guys, why don't we turn our _collection of multiple files_ into a *collection of multiple files*!!" Extract the ^above with this: cat pics.tar.gz.??? | tar xzv ^extract on any Unix - no need to install junkware! (If you must make proprietary software, at least make it do something *new*) if [ -e windows ]; then use 7-Zip

Create a bunch of dummy text files

Avoiding a for loop brought this time down to less than 3 seconds on my old machine. And just to be clear, 33554432 = 8192 * 4086.

Do quick arithmetic on numbers from STDIN with any formatting using a perl one liner.

Good for summing the numbers embedded in text - a food journal entry for example with calories listed per food where you want the total calories. Use this to monitor and keep a total on anything that ouputs numbers. Show Sample Output

Split SQL/TXT File into 12000 Lines Each File and then Add .sql Extension to File

For some reason split will not let you add extension to the files you split. Just add this to a .sh script and run with bash or sh and it will split your text file at 12000 lines for each file and then add a .sql extension to the file name.
This is sample output - yours may be different.

split -l 12000 -a 5 database.sql splited_file i=1 for file in splited_file* do mv $file database_${i}.sql i=$(( i + 1 )) done

Split a file into equal size chunks and archive to (e)mail account.

This is just a little snippit to split a large file into smaller chunks (4mb in this example) and then send the chunks off to (e)mail for archival using mutt. I usually encrypt the file before splitting it using openssl: openssl des3 -salt -k <password> -in file.tgz -out file.tgz.des3 To restore, simply save attachments and rejoin them using: cat file.tgz.* > output_name.tgz and if encrypted, decrypt using: openssl des3 -d -salt -k <password> -in file.tgz.des3 -out file.tgz edit: (changed "g" to "e" for political correctness)

split -b4m file.tgz file.tgz. ; for i in file.tgz.*; do SUBJ="Backup Archive"; MSG="Archive File Attached"; echo $MSG | mutt -a $i -s $SUBJ [email protected](E)mail.com

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.

Switch to the previous branch used in git(1)

Very useful if you keep switching between the same two branches all the time.

Convert a bunch of HTML files from ISO-8859-1 to UTF-8 file encoding in a folder and all sub-folders

This is my first attempt at converting all HTML files to UTF-8 file encoding, including all subfolders. Theres probably a much more compact way to do it, but I'm quite proud of it with my windows background ;)

Randomize lines in a file

Works in sort (GNU coreutils) 7.4, don't know when it was implemented but sometime the last 6 years.

Automatically tunnel all ports of running docker instances in boot2docker

It requires https://jqplay.org/, that comes with brew: brew install jq

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Recompress all files in current directory from gzip to bzip2

Find all .gz files and recompress them to bz2 on the fly. No temp files. edit: forgot the double quotes! jeez!

Convert all WMF images to SVG recursively ignoring file extension case

This assumes you have the package installed necessary for converting WMF files. On my Ubuntu box, this is libwmf-bin. I used this command, as libwmf is not on my wife's iMac, so I archived the directories containing the WMF files from OS X, ran them on my Ubuntu box, archived the resulting SVGs, and sent them back to her. Quick, simple and to the point. Searches directories recursively looking for extensions ignoring case. This is much more readable and clean than -exec for find. The while loop also gives further flexibility on complex logic. Also, although there is 'wmf2svg --auto', it expects lowercase extensions, and not uppercase. Because I want to ignore case, I need to use the -o option instead. Works in ZSH and BASH. Haven't tested in other shells.

Extract tar.gz file with original permission

-x, --extract, --get extract files from an archive -p, --preserve-permissions, --same-permissions extract information about file permissions (default for superuser) -f, --file=ARCHIVE use archive file or device ARCHIVE -v, --verbose verbosely list files processed

Use AWS CLI and JQ to get a list of instances sorted by launch time

You can do the filtering natively in the aws cli, without using jq (although jq is awesome!)

This is how you should push a string in a command's stdin.

Don't do this: $echo word | command Using a bash "here strings" and "here documents" look leeter than piping echo into the command. Also prevents subshell execution. Word is also expanded as usual.
