bash scripting --- some help needed
Hi all,
I want to write a bash script for some task that will save a lot of time. Basically given the following file format: ================================================== The following list of files implement this module. List of files: ... //repository/usr/local/file1 ... //repository/usr/local/dir/file2 ... //repository/usr/tmp/file3 some other description. =================================================== I need to read this file and create a backup of each listed file. But I am having a hard time reading file path and names. In the above file, === line is not present in the file (just here for clarity). So in the above example, I need to create the following backups in /usr/local/backup directory: /usr/local/file1 -> /usr/local/backup/usr/local/file1.bk /usr/local/dir/file2 -> /usr/local/backup/usr/local/dir/file2.bk /usr/tmp/file3 -> /usr/local/backup/usr/tmp/file3.bk After creating backups, I need to change the group of actual files to "backedUp". I also want to echo proper messages. So I copy a file, if it is successful (based on the error return code in bash), I want to echo "created backup of this file to this file". If any error occurs in between, I need to roll back all changes. So the entire operation is atomic. I also want some way to verify output in the end. Any help on this is highly appreciated. Raj |
so where are you actually stuck? (those ==='s are not for clarity btw..!) if you have this simple list file then accessing each line is just down to the contents of a for loop:
Code:
for file in $(cat /blah/something/backups) I really hope this is a real question and not homework... |
