how to use temporary files?


my dilema is that:
i am trying to write a shell script 'shortcut' that does the following:

[nruhomutally@dblsys bin]$./shortcut -a myls ls -lart # Associates the tag 'myls' with the command 'ls -lart'
[nruhomutally@dblsys bin]$./shortcut myls # runs 'ls -lart'
[nruhomutally@dblsys bin]$./shortcut -d myls
OK, shortcut 'myls' deleted
[nruhomutally@dblsys bin]$
[nruhomutally@dblsys bin]$.shortcut -l myls
Shortcut 'myls' = ls -lart
[nruhomutally@dblsys bin]$

So is your question about temporary files, or about how to write the script?

If your question is about temporary files, what is your question?

If your question is about how to write the script, and you don't know much about shell scripting, get cracking and learn it! (grins) Google for

Code:
bash tutorial
Otherwise, maybe you want to post the script you have written so far and ask a specific question about it.

Hope this helps you get started.

alias rm="rm -rf" //changes every instance of rm to rm -rf
alias -a //removes all aliases
alias -t //lists all tracked aliases
alias -x //lists all exported aliases
unalias rm //removes the alias above

They don't work for me either. Some of them (not all) work better in ksh, but I'll bet you're using bash.

Try these:

Code:
alias rm="rm -rf" # changes every instance of rm to rm -rf
alias             # lists   all aliases
unalias -a        # removes all aliases
unalias rm        # removes the alias for rm

edit your .bashrc file in your home directory and add an alias:

Code:
cd ~
vi .bashrc
Now you need to add this line under the other aliases:

Code:
alias myls='ls -lart'
Write and quit this file (:wq) and now you need to re read this file in order to use it:

Code:
source .bashrc
now you can just type: myls and it should work like a regular command.

After you've made custangro's recommended changes to the .bashrc file in your home directory and you've typed source .bashrc, when you type myls, what error message do you get?
