Commands using mv

each number in a file name gets expanded to the number of digets provided as arg_1 of the arguments in rjust_file_nums. Put the funciton in the .bashrc file. Be sure to $ source ~/.bashrc so that the function will be accessible from bash.

A simple way to rename a set of files to a unique, randomized file name.

This lets you replace a file or directory and quickly revert if something goes wrong. For example, the current version of a website's files are in public_html. Put a new version of the site in public_html~ and execute the command. The names are swapped. If anything goes wrong, execute it again (up arrow or !!).

this alternative shows the differences as they occur so that they are made plain

Sometimes, you don't want to just replace the spaces in the current folder, but through the whole folder tree - such as your whole music collection, perhaps. Or maybe you want to do some other renaming operation throughout a tree - this command's useful for that, too.

To rename stuff through a whole directory tree, you might expect this to work:

for a in `find . -name '* *'`;do mv -i "$a" ${a// /_};done

No such luck. The "for" command will split its parameters on spaces unless the spaces are escaped, so given a file "foo bar", the above would not try to move the file "foo bar" to "foo_bar" but rather the file "foo" to "foo", and the file "bar" to "bar". Instead, find's -execdir and -depth arguments need to be used, to set a variable to the filename, and rename files within the directory before we rename the directory.

It has to be -execdir and won't work with just -exec - that would try to rename "foo bar/baz quux" to "foo_bar/baz_quux" in one step, rather than going into "foo bar/", changing "baz quux" to "baz_quux", then stepping out and changing "foo bar/" into "foo_bar/".

To rename just files, or just directories, you can put "-type f" or "-type d" after the "-depth" param.

You could probably safely replace the "mv" part of the line with a "rename" command, like rename 'y/ /_/' *, but I haven't tried, since that's way less portable.

for music file of mp3.zing.vn

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

File names with spaces may cause problems, this command could help to avoid that.

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.
