A quick question:
How do I run several commands in Sequence or all at once?
If you need to run several commands chain them with a ; (semi colon). It is a control operator or metacharacter.
Commands separated by a ; are executed sequentially; the shell waits for each command to terminate in turn. The return status is the exit status of the last command executed.
Run command all at once
To run several commands all at once by putting an ampersand & at the end of the command line. For example start backup script:
# /root/ftpbackup.sh &
Now you don't have to wait finishing /root/ftpbackup.sh script.
Putting it all together
There might be thousands of *.bak file. You need to goto each directory and list all files in /tmp/list directory:
# for d in "/home/sales /home/dbs /data1"; do find $d -iname "*.bak" >> /tmp/list; done &
