I often run some command that takes a while to finish. By putting the say command afterward, I get an audio notification.

Please note that this command (say) only works on Mac OS X and not Linux.

Functions: ls read rm tar

Compresses each file individually, creating a $fileneame.tar.gz and removes the uncompressed version, usefull if you have lots of files and don't want 1 huge archive containing them all. you could replace ls with ls *.pdf to just perform the action on pdfs for example.

cryptmount -m <name>
2012-01-17 18:02:47
User: totti

In order to create a new encrypted filing system managed by cryptmount,

you can use the supplied 'cryptmount-setup' program, which can be used

by the superuser to interactively configure a basic setup.

Alternatively, suppose that we wish to setup a new encrypted filing

system, that will have a target-name of "opaque". If we have a free

disk partition available, say /dev/hdb63, then we can use this directly

to store the encrypted filing system. Alternatively, if we want to

store the encrypted filing system within an ordinary file, we need to

create space using a recipe such as:

dd if=/dev/zero of=/home/opaque.fs bs=1M count=512

.

cryptmount --generate-key 32 opaque

.

cryptmount --prepare opaque

.

mke2fs /dev/mapper/opaque

.

cryptmount --release opaque

.

mkdir /home/crypt

.

cryptmount -m opaque

.

cryptmount -u opaque

Files saved on a windows machine use different ascii characters for lines turns. When viewing such files in VI the will most often have a ^M(control-VM) character at the end of each line. This command will remove all occurrences of that character

Nothing special about hashing here, only the use of cut, I think, could result at fewer keystrokes.

Depending on your installation, when you run ps you will only get the first 40 or so characters displayed. In order to view the entire string, use /usr/ucb/ps on Solaris.
