Commands tagged mount (30)

  • `mount -o remount` doesn't pick up new NFS options (eg. timeo, soft, retrans, etc) so you need to do a full mount/remount cycle. This one-liner makes it quick and easy :) Update your fstab with the new options, then run it. Show Sample Output

    for P in $(mount | awk '/type nfs / {print $3;}'); do echo $P; sudo umount $P && sudo mount $P && echo "ok :)"; done

  • 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 For detail see sample output Show Sample Output

    cryptmount -m <name>

connects to a serial console
cu (call UNIX) establishes a full-duplex connection to another machine (*BSD) using a serial console. It becames more useful than screen if you have to send a BREAK signal. using cu just type "~#". $man cu

kill all processes using a directory/file/etc
This command will kill all processes using a directory. It's quick and dirty. One may also use a -9 with kill in case regular kill doesn't work. This is useful if one needs to umount a directory.

Get MX records for a domain
command is shorter, output unnecessary longer

Save a file you edited in vim without the needed permissions (no echo)
Write a file you edited in Vim but that you do not have the permissions to write to (unless you use sudo.) Same as #1204 but without the echo to stdout that I find annoying.

Extract audio from Mythtv recording to Rockbox iPod using ffmpeg
There are some pretty good live performances on late night TV. With Mythtv I record David Letterman, Jimmy Fallon, and Conan nightly all in HD from over the air broadcasts. If I find a live performance I like I copy it to my Rockboxed iPod using this command. The Rockbox firmware knows how to downmix 5.1 audio. The command above extracts the audio from the video starting at 58 minutes and 15 seconds. It ends at the end of the file since this was the last performance of the recording. The command creates an ac3 file. I copy the ac3 file to my Rockbox iPod and rock on.

Copy/move a bunch of files to dot files and back
