rm alias

hi ,

i want to make alias for rm to be like that :

alias rm 'rm -iv $A | mailx -s "file $A deleted" sherif@hotmail.com'

where A is the input file i will run the rm command on it as example

rm sherif so when that go to the alias it should run like that :

rm -iv $A (where A will bethe input file sherif)  | mailx -s "file $A (where A will bethe input file sherif) deleted" sherif@hotmail.com

in another word i want to make that input file name sherif  to be variable for the alias of the rm command .

hope you can get what i mean , please feed me back how i can make it i need it for emergency thing thanks    

RE: rm alias

Why are you piping the output of the rm command into the email?  Normally rm doesn't display anything.  No harm in doing it though I suppose.

Aliases are not ideal when you need to use parameters in the middle of the command; instead you should try using a function.

Remember also that rm isn't always just used to remove one file, and sometimes people will use options like -rf, so you should use "$@" to include all supplied parameters.


function rm
    rm -iv "$@"
    mailx -s "files $@ deleted" sherif@hotmail.com </dev/null

This also assumes that the rm commanded succeeded, which is not necessarily true.

I guess the -v option probably makes it display something...

RE: rm alias

RE: rm alias

sorry i just see your replay , can feed me back how to use the functions ?

RE: rm alias

What shell are you using?  (i.e. what is the output of ps -fp $$?

Try pasting the example I gave above into your ~/.profile, then log out and log back in again.

Type typeset -f to see what functions you have loaded to make sure it has loaded properly.

Alternatively you can put it in a separate file, for example myfuncs.sh, and then load it like this:


. ./myfuncs.sh
