Only shows files with actual changes to text (excluding whitespace). Useful if you've messed up permissions or transferred in files from windows or something like that, so that you can get a list of changed files, and clean up the rest.

For example:

rar a -v10M nameofrar filestorar

This will create an archive of the filestorar divided into 10MB volumes

say -f file.txt
say `cat /path/to/textfile.txt`

This is helpful for shell scripts, I use it in my custom php install script to schedule to delete the build files in 3 hours, as the php install script is completely automated and is made to run slow.

Does require at, which some environments without crontab still do have.

You can add as many commands to the at you want. Here's how I delete them in case the script gets killed. (trapped)

atq |awk '{print $1}'|xargs -iJ atrm J &>/dev/null

This command runs your shell script in the background with no output of any kind, and it will remain running even after you logout.

The coolest way I've found to backup a wordpress mysql database using encryption, and using local variables created directly from the wp-config.php file so that you don't have to type them- which would allow someone sniffing your terminal or viewing your shell history to see your info.

I use a variation of this for my servers that have hundreds of wordpress installs and databases by using a find command for the wp-config.php file and passing that through xargs to my function.

I used this to copy all PDFs recursively to a selected dir

This allows the output to be sorted from largest to smallest in human readable format.

Nothing advanced, it just finds filenames that are stored with ISO-8859-1 characters and and converts those into UTF-8. Recommended to use without the --notest flag first so you can see what will be changed.

Using a GUI file managers you can merge directories (cut and paste). This command roughly does the same (it doesn't ask for confirmation (no problem for me) and it doesn't clean up the empty SRC directories (no problem, trivial).

probably does the same:

cp -l SRC TARGET; rm -rf SRC
ps aux | grep [c]ommandname
SELECT relname, reltuples, pg_relation_size(relname) FROM pg_class r JOIN pg_namespace n ON (relnamespace = n.oid) WHERE relkind = 'r' AND n.nspname = 'public' ORDER BY relname;

Postgresql specific SQL

- to show count of ALL tables including relation-size (pg_relation_size = used space on filesystem)

- might need a VACUUM ANALYZE before showing all counts correctly !
