Check These Out

list file descriptors opened by a process

Email a file to yourself
This works on Solaris 10.

mount an iso

Notepad in a browser (type this in the URL bar)
It doesn't save your notes, but it's great for jotting something down quickly.

Send an email from the terminal when job finishes
Might as well include the status code it exited with so you know right away if it failed or not.

Restart openssh-server on your Synology NAS from commandline.
The correct way to restart openssh-server on your synology nas.

Update zone file Serial numbers
Will edit *.db files in the same directory with todays date. Useful for doing a mass update to domains on a nameserver, adding spf records, etc. Looks for a string starting with 200 or 201 followed by 7 numbers, and replaces with todays date. This won't overwrite Ip's but i would still do some double checking after running this. Make sure your server's date is correct, otherwise insert your own serial number. $rndc reload should usually follow this command.

Printing multiple years with Unix cal command
print multiple increasing years using cal - calendar -. You can also try $seq Start Increment End

run command on a group of nodes in parallel redirecting outputs
Do the same as pssh, just in shell syntax. Put your hosts in hostlist, one per line. Command outputs are gathered in output and error directories.
