Linux - Tape Backup/Restore

SCSI tape drive Rewind : /dev/st0 No-Rewind : /dev/nst0 BACKUP ====== Backup directory /www and /home with tar command (z - compressed): # tar -czf /dev/st0 /www /home To back up the entire file system using tar to a SCSI tape drive, excluding the /proc directory: # tar -cpf /dev/st0 / --exclude=/proc (-p switch indicates that we want to preserve the file permissions) (-M switch, for multi-volume if the backup will not fit on a single tape) The following line backs up all the files and directories listed in MyFiles, the /root directory, and all of the iso files in the /tmp directory: # tar -cpf /dev/st0 -T MyFiles /root /tmp/*.iso (-T switch, put the files and directories that you want to archive in a text file) (note that the tar -T (or files-from) command cannot accept wildcards. Files must be listed explicitly.) You could also execute a script to search the system and then build a list. Here is an example of such a script: #!/bin/sh cat MyFiles > TempList find /usr/share -iname

Linux - Change console color

Quoted from http://www.frozenblue.net/tools/howtos /?v=redhat-8-console-fonts&op=printable # vi $HOME/.dir_colors # Configuration file for the color ls utility # COLOR needs one of these arguments: 'tty' colorizes output # to ttys, but not pipes. 'all' adds color characters to # all output. 'none' shuts colorization # off. COLOR tty # Extra command line options for ls go here. # Basically these ones are: # -F = show '/' for dirs, '*' for executables, etc. # -T 0 = don't trust tab spacing when formatting ls output. OPTIONS -F -T 0 # Below, there should be one TERM entry for each # termtype that is colorizable TERM linux TERM console TERM con132x25 TERM con132x30 TERM con132x43 TERM con132x60 TERM con80x25 TERM con80x28 TERM con80x30 TERM con80x43 TERM con80x50 TERM con80x60 TERM cons25 TERM xterm TERM rxvt TERM xterm-color TERM color-xterm TERM vt100 TERM dtterm TERM color_xterm # EIGHTBIT, followed by '1' for on, '0'
