VIB is a BASH SHELL SCRIPT Wrapper for the VI editor that backs up the files being edited to a directory (depending on the configurable size of the file) and provides better revision control and file recovery.
# vib -h
This tool is designed to create backup files of any file edited using the VI (VIM) editor. It allows you to backup the files in a default subdirectory of /opt/vib, or the option to create backups in the current working directory (not advised)
By default, VIB adds the user name to the file name and it also allows you to add the directory name to the file name that is saved if you back it up to a specified destination directory.
The script usage options are:
# vib -?

[V][I] [B]ackup Wrapper
by ben@datastorageguy.com
usage:
# vi [-h|-e|-d|-l|-n|-r|-t|-v] <file>
-h Display detailed help/usage
-e Enable VIB
-d Disable VIB
-l Enable add Last Modification Date (Default is Enabled)
-n Disable all Last Modification prepending
-r Uninstall-Reset the alias to default
-t FORCE Enable add Last Modification Date to <file>
*note: Default for any scripts
-v Verbose (debug) output
Installing VIB involves:
- manually copying the file to /usr/local/bin (or your preferred directory)
- Using the 'vib' command to edit files, OR
- Enable vib via the '-e' option to alias vi and vim command
# vib -e
-------------------------------------------------------------------
ENABLED VIB
REMOVED FILE: /var/tmp/.novib
-------------------------------------------------------------------
How we see the alias
# alias |grep vib
alias vi='/usr/local/bin/vib'
By default VIB appends the date/timestamp to the top of the file for BASH/KSH/PERL/SH Scripts Example. Viewing file teststuff.sh and adding 'echo World' to the end of the file:
#vi teststuff.sh
#!/bin/bash
###################################################################
# Script to test stuff
#################################################
echo "Hello"
echo "World"
#
Re-editing the file and now wee see the last modification time!
#!/bin/bash
################################################
#LAST MODIFIED: 2021-03-24 20:32:02
#################################################
echo "Hello"
echo "World"
This section illustrates using VIB with the default backup directory of /opt/vib
In other words you keep all backups in one location
Set the following VIB options to
- Configure the VIB Backup Directory
- Set the USEDIR option to 0 so that files are kept in BACKUP_DIRECTORY
BACKUP_DIRECTORY=/opt/vib
USEDIR=0
Now in this example we show that there are no files in /opt/vib
#
ls -al /opt/vib
total 8
drwxr-xr-x 2 root root 4096 Jul 23 15:05 .
drwxrwxrwt 3 root root 4096 Jul 23 15:05 ..
#
Now we list a testfile in the current user HOME directory And verify there is some content in the file
# pwd
/home/ovnuser
# ls -al testfile
-rw-r--r-- 1 root root 43 Jul 23 14:11 testfile
#
# cat testfile
here is some stuff
#
We edit the file now using vib and add some stuff to it.
Note we see there is a confirmation to save the changes
# vib testfile
..
<adding 'here is some more stuff'>
:wq!
Commit Changes [n] y

Now we see that there is data in the new 'testfile'
# cat testfile
here is some stuff
here is some more stuff
#
Looking in the VIB BACKUP_DIRECTORY now shows we see a backup copy of the file
# ls -al /opt/vib
total 44
drwxr-xr-x 2 ovnuser wheel 4096 Jul 23 14:12 .
drwxrwxrwx 8 root root 4096 Jul 23 14:13 ..
-rw-r--r-- 1 root root 43 Jul 23 14:12 testfile.bpatridg.1
Looking at the content of the file we see that there is the ORIGINAL file data.
#
# cat /var/tmp/viblog/testfile.bpatridg.1
here is some stuff
Editing the file one more time and adding additional content
# vi testfile
..
<edit file adding 'adding even more stuff'>
:wq!
Commit Changes [n] y
Changes Saved ...
#
# cat testfile
here is some stuff
here is some more stuff
adding even more stuff
Now we see there is another backup copy of the file in the BACKUP_DIRECTORY
# ls -al /var/tmp/viblog
total 16
drwxr-xr-x 2 ovnuser trc 4096 Jul 23 14:18 .
drwxrwxrwx 8 root root 4096 Jul 23 14:17 ..
-rw-r--r-- 1 root root 43 Jul 23 14:17 testfile.bpatridg.1
-rw-r--r-- 1 root root 19 Jul 23 14:17 testfile.bpatridg.2
#
# cat /var/tmp/viblog/testfile.bpatridg.2
here is some stuff
here is some more stuff

This section describes saving all files in a designated backup location while including the PATH TO THE FILE in the backup file name.
Meaning, the "root" filesystem directory (/) is the BACKUP_DIRECTORY
For Example
The system 'user' directory is /home/ovnuser When backing up the file it will write to $BACKUP_DIRECTORY/home/ovnuser
Below we set:
- The BACKUP_DIRECTORY
- The USEDIR option to 1 which sets the BACKUP_DIRECTORY as the "root" directory
BACKUP_DIRECTORY=/var/tmp/viblogs
USEDIR=1
Now we have cleared the BACKUP_DIRECTORY (for this example) and we verify it is empty
ls -al /var/tmp/viblogs
drwxr-xr-x 2 root root 4096 Jul 23 16:24 .
drwxrwxrwt 4 root root 4096 Jul 23 15:11 ..
#
Next we list a file in the current use directory, and then view content in that file
#
# ls -al /home/ovnuser/testfile
-rw-r--r-- 1 root root 43 Jul 23 14:11 testfile
#
# cat testfile
here is some stuff
here is some more stuff
#
Next we edit the testfile and add some temporary content
# vi testfile
..
<adding 'adding a bunch more stuff again'>
:wq!

# cat testfile

adding a bunch more stuff again
We see that there is a backup of the file edited contains 2 subdirectories to the file!
#
# cd /var/tmp/viblog
# ls -Al
drwxr-xr-x 2 root root 4096 Jul 23 16:24 .
