Functions: awk cut find sed sort uniq xargs

* Find all file sizes and file names from the current directory down (replace "." with a target directory as needed).

* sort the file sizes in numeric order

* List only the duplicated file sizes

* drop the file sizes so there are simply a list of files (retain order)

* calculate md5sums on all of the files

* replace the first instance of two spaces (md5sum output) with a \0

* drop the unique md5sums so only duplicate files remain listed

* Use AWK to aggregate identical files on one line.

* Remove the blank line from the beginning (This was done more efficiently by putting another "IF" into the AWK command, but then the whole line exceeded the 255 char limit).

>>>> Each output line contains the md5sum and then all of the files that have that identical md5sum. All fields are \0 delimited. All records are \n delimited.

This command will delete all files and folders except 'skipme'. it could be a file or a folder.

When you do a ls -1 | xargs rm it wouldn't workd because those files have spaces. So you must use

find -print0 and xargs -0

Functions: grep wget xargs

This script can be used to download enclosed files from a RSS feed. For example, it can be used to download mp3 files from a podcasts RSS feed.

echo '#! /usr/bin/ksh\ncat $2 | openssl dgst -sha256 | read hashish; if [[ $hashish = $1 ]]; then echo $2: OK; else echo $2: FAILED; fi;' > shacheck; chmod +x shacheck; cat hashishes.sha256 | xargs -n 2 ./shacheck;

User: RAKK
Functions: cat chmod echo read xargs

This command is used to verify a sha256sum-formatted file hash list on IBM AIX or any other UNIX-like OS that has openssl but doesn't have sha256sum by default. Steps:

1: Save to the filesystem a script that:

A: Receives as arguments the two parts of one line of a sha256sum listing

B: Feeds a file into openssl on SHA256 standard input hash calculation mode, and saves the result

C: Compares the calculated hash against the one received as argument

D: Outputs the result in a sha256sum-like format

2: Make the script runnable

3: Feed the sha256sum listing to xargs, running the aforementioned script and passing 2 arguments at a time

To export into another backends style, just change backend to one of: access, sybase, oracle, postgres, mysql and sqlite

Solves these pesky errors you see in the Apache log:

[Fri Jun 28 17:51:00 2013] [emerg] (28)No space left on device: Couldn't create accept lock (/monsoon/opt/apache2/logs/accept.lock.356) (5)

Naturally, can be used to get rid of other semaphores. Note: change the apache user in accordance to your ENV.

On Linux substitute pbpaste with `xsel --clipboard --output` or `xclip -selection clipboard -o` (untested)

User: HerbCSO
Functions: cut find sort stat xargs

Goes through all files in the directory specified, uses `stat` to print out last modification time, then sorts numerically in reverse, then uses cut to remove the modified epoch timestamp and finally head to only output the last 10 modified files.

Note that on a Mac `stat` won't work like this, you'll need to use either:

find . -type f -print0 | xargs -0 stat -f '%m%t%Sm %12z %N' | sort -nr | cut -f2- | head

or alternatively do a `brew install coreutils` and then replace `stat` with `gstat` in the original command.

Recursively list all files in the current directory & get their md5sum, even if the filename has bad characters.

ssh user@remotehost "find basedir -type d" | xargs -I {} -t mkdir -p {}
2013-07-17 07:14:32
User: neomefistox
Functions: mkdir ssh xargs

The directories are created in the local host with the same structure below of a remote base directory, including the 'basedir' in case that it does not exists.

You must replace user and remotehost (or IP address) with your proper values

ssh will ask for the password of the user in remotehost, unless you had included properly your hostname in the remote .ssh/known_hosts file.

Functions: awk find rm sort xargs

If you have a directory with lot of backups (full backups I mean), when it gets to some size, you could want to empty some space. With this command you'll remove half of the files. The command assumes that your backup files starts with YYYYMMDD or that they go some alphabetical order.

User: glaudiston
Functions: cd diff find md5sum xargs

This is usefull to diff 2 paths in branches of software, or in different versions of a same zip file. So you can get the real file diff.
