It eases the way of creating cron jobs of backup scripts. Just put this line as cron job, and all your backups are called sequentially. Allows you to forget, when in time, call this backup, just focus on your scripting. Also maintains the way of calling a single backup script when It's needed.
This command is for producing GNU sha256sum-compatible hashes on UNIX systems that don't have sha256sum but do have OpenSSL, such as stock IBM AIX. 1.- Saves a wrapper script for UNIX find that does the following: A.- Feeds a file to openssl on SHA256 hash calculation mode B.- Echoes the output followed by the filename 2.- Makes the file executable 3.- Runs find on a directory, only processing files, and running on each one the wrapper script that calculates SHA256 hashes Pending is figuring out how to verify a sha256sum file on a similar environment.

Find's all png's in the current folder and all of its children pngcrushes all results. Destructive.
When trying to find an error in a hosted project it's interesting to find out how the source is organized: Are there .inc files? Or .php files only? Or .xml files that probably contain translated texts? Show Sample Output

"find ./ ..." could be replaced with "find $PWD ..." to display absolute path instead of relative path. Show Sample Output
Display a list of local shell scripts soft-linked to /usr/local/bin Put local shell scripts to local ~/bin/ directory and soft-link them to /usr/local/bin/ which is in the $PATH variable to run them from anywhere. Show Sample Output
* 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.
note that sed -i is non-standard (although both GNU and current BSD systems support it)
Can also be accomplished with
find . -name "*.txt" | xargs perl -pi -e 's/old/new/g'
