Commands tagged recursive

Output of this command is the difference of recursive file lists in two directories (very quick!).

To view differences in content of files too, use the command submitted by mariusbutuc (very slow!):

.flac is the filetype.

/Volumes/Music/FLAC is the destination.

extracts path to each md5 checksum file, then, for each path, cd to it, check the md5sum, then cd - to toggle back to the starting directory. greps at the end to remove cd chattering on about the current directory.

-exec sh -c 'var={}; do something with var' lets you do things in a sub-shell

while it's faster to type, I'm not sure if dozens of subshells execute quicker than the while loops.

finds all epub files in the current directory and all child directories and converts them to .mobi format.

all of the ebook-convert -options are optional; the only parameters you are required to pass are the incoming file and the outgoing file, with the extension.

Has been tested on Ubuntu 10.10

This will recursively add files/directories in SVN.

Usage:

or

then:

Notice: It might not work properly, and not all files could get added.

Since there is a limit on characters, I couldn't add failure/success notices.

If you want failure/success notices, download Terminal Enhancements (http://tenhancements.tk/ )

It is included on Base Features

Corrected.

This will handle the case that the filename has spaces or other characters that need to be escaped.

This command is recursive and will delete in all directories in ".". It will find and delete all files not specified with ! -name "pattern". In this case it's file extensions. -type f means it will only find files and not directories. Finally the -delete flag ask find to delete what it matches. You can test the command by running it first without delete and it will list the files it will delete when you run it.

recursive find and replace. important stuff are grep -Z and zargs -0 which add zero byte after file name so sed can work even with file names with spaces.

an alternative

find . -type f -iname '*.flac' # searches from the current folder recursively for .flac audio files

| # the output (a .flac audio files with relative path from ./ ) is piped to

while read FILE; do FILENAME="${FILE%.*}"; flac -cd "$FILE" | lame -b 192 - "${FILENAME}.mp3"; done

# for each line on the list:

# FILE gets the file with .flac extension and relative path

# FILENAME gets FILE without the .flac extension

# run flac for that FILE with output piped to lame conversion to mp3 using 192Kb bitrate

The above command will set the GID bit on all directories named .svn in the current directory recursively. This makes the group ownership of all .svn folders be the group ownership for all files created in that folder, no matter the user.

This is useful for me as the subversion working directory on my server is also the live website and needs to be auto committed to subversion every so often via cron as well as worked on by multiple users. Setting the GID bit on the .svn folders makes sure we don't have a mix of .svn metadata created by a slew of different users.

Works recusivley in the specified dir or '.' if none given.

Repeatedly calls 'find' to find a newer file, when no newer files exist you have the newest.

In this case 'newest' means most recently modified. To find the most recently created change -newer to -cnewer.

Changed out the for loop for an xargs. It's a tad shorter, and a tad cleaner.

Recursively replace a string in files with lines matching string. Lines with the string "group name" will have the first > character replaced while other > characters on other lines will be ignored.

sometimes if directories are too deep, chmod -R fails... in those cases, a find comes in most handy :)
