Get/Execute bash shell alias

[CJason]

I have an alias set in my bash shell, say:

THISALIAS='this.exe'

In my perl script, I want to execute this alias...something like:

system("THISALIAS");

Any ideas on how I can access the alias in order to execute it?? Thanks in advance!

Do u now the alias fullpath, if yes you could just use it like

my $alias = "/fullpath/this.exe";
system($alias);

if you don't know the alias full path, decription, you could check it via perl script and then use the value of it within system

my $alias= `echo $THISALIAS`; 
# check the command in your unix system, syntax may vary
system($alias);

I have found to NEVER rely on alias and path variables that come from things like .profile/.login, that are not always available via crons and such. I prefer just to set everything myself in my scripts.

dmazzini, unfortunately, alias variables don't show up with `echo $THISALIAS`...an alias is not an environmental variable. From a bash shell, you would get the alias by: "alias THISALIAS"...but, I can't seem to see an alias variable within a perl script.

travs69, fortunately, I have the ability to make these aliases environmental variables. However, I wanted to see if I could save a little work by accessing the "already there" alias variables.
