Commands using mv

For those files in current folder that would be shown in `ls *ext`, for some extension ext, move/rename that file removing the .ext suffix from the file name.

It uses Bash's parameter substitution, as seen in

(for analog use in prefix, see http://tldp.org/LDP/abs/html/parameter-substitution.html#PSOREX2 )

diff originalfile updatedfile > my.patch

When a large maven release goes wrong, by deploying just some of the artifacts letting others behind, some projects got wrong SNAPSHOT versions. This command comes to help!

Tip: replace sed's regex by your version numbers

Rename all mp4 files with crc32 information.

Sometimes in a hurry you may move or copy a file using an already existent file name. If you aliased the cp and mv command with the -i option you are prompted for a confirmation before overwriting but if your aliases aren't there you will loose the target file!

The -b option will force the mv command to check if the destination file already exists and if it is already there a backup copy with an ending ~ is created.

Deletes unneeded files after every step and allows to use a color other than yellow at the last position.

You can also save EXIF information by copying it to temp.jpg:

Use case: folder with flac files with tree structure ../artist/album/number-title.flac

1) convert flac->mp3 in the same folder: http://www.commandlinefu.com/commands/view/6341/convert-all-.flac-from-a-folder-subtree-in-192kb-mp3

2) search for mp3 files and recreate tree structure to another path: http://www.commandlinefu.com/commands/view/8853/copy-selected-folder-found-recursively-under-src-retaining-the-structure

3) move all mp3 files to that new folder: this command

This is a better version, as it does no command piping, uses for instead of while loops, which allows for a list of files in the current working directory to be natively processed. It also uses the -v/verbose option with mv to let you know what the command is doing.

While the command does exactly the same in a better way, I would modify the sed option to replace spaces with underscores instead, or dashes.

Please note that you'll receive errors with this command as it tries to rename files that don't even have spaces.

This is an alternative to: http://www.commandlinefu.com/commands/view/8761/renames-all-files-in-the-current-directory-such-that-the-new-file-contains-no-space-characters.

Replaces space in a file with a underline

Give files a random name (don't ask why :-)

The function will rename files but maintain their extensions.

BUG: If a file doesn't have an extension it will end up with a dot at the end of the name.

The parameter '8' for pwgen controls the length of filenames - eight random characters.

You can replace "." with your folder

That is an alternative to command 8368.

Command 8368 is EXTREMELY NOT clever.

1) Will break also for files with spaces AND new lines in them AND for an empty expansion of the glob '*'

2) For making such a simple task it uses two pipes, thus forking.

3) xargs(1) is dangerous (broken) when processing filenames that are not NUL-terminated.

4) ls shows you a representation of files. They are NOT file names (for simple names, they mostly happen to be equivalent). Do NOT try to parse it.

Recursive version:

without sed, but has no problems with files with spaces or other critical characters

as commented by Urk...

Rotates log files with "gz"-extension in a directory for 7 days and enumerates the number in file name.

i.e.: logfile.1.gz > logfile.2.gz

I needed this line due to the limitations on AIX Unix systems which do not ship with the rename command.

find pictures recursively in a specified folder and renames the file name to originalname_containingfoldername.jpg

Recursively find php files and replace tab characters with spaces.

Options:

"\*.php" -- replace this with the files you wish to find

"expand" -- replace tabs with spaces (use "unexpand" to replace spaces with tabs)

"-t4" -- tabs represent 4 spaces

Note: The IFS="" in the middle is to prevent 'read' from eating leading/trailing whitespace in filenames.

Recursively changes every file case to lowercase

Renames files eliminating suffix, in this case everything after "-" is cutted. Just change "-" with the character you need.

If you want to turn a Git repo into the origin that folks can push to, you should make it a bare repository. See: http://stackoverflow.com/questions/2199897/git-convert-normal-to-bare-repository
