kill script using alias name
Hi,

I am using the below command to kill the firefox process i have opened in Redhat 5.

Code:
ps -ef|grep fire|grep -v grep|awk '{print $2}'|xargs kill -9

If i execute the above command in terminal it works good and kills session.

but when i use alias for that it is not working.

Code:
alias kill_firefox="ps -ef|grep fire|grep -v grep|awk '{print $2}'|xargs kill -9"

when i run kill_firefox in terminal, i am getting the output as,

Code:
kill : can't find process "root"
killed


But my firefox session still opened and it works.

Share ur thoughts.

Hi.

Also:
Quote:
Aliases are not expanded when the shell is not interactive, unless the
expand_aliases shell option is set using shopt ...

For almost every purpose, aliases are superseded by shell functions.
-- excerpt from man bash q.v., which has more to say on aliases, mostly to the point that one should be using functions instead.

Best wishes ... cheers, drl
