如何将 tar 命令添加到备份脚本

Question

I am trying to add a tar command to the /test/backup/backup.sh that creates a full backup of everything in my file system except the /text directory to a file called /test/backup.dat. Plus redirect the standard output from this command to a file called /test/backuplog.txt. Redirect the standard error from this command to a file called /test/errlog.txt. How would I get this done? Thank you.

Answer 1

You can do that by adding this at the end of each command

<command> >>/test/backuplog.txt 2>>/test/errlog.txt

also you need to make sure that /test/backuplog.txt and /test/errlog.txt is writable
