exec perl in expect script yields "invalid command"

Shell Programming and Scripting
1

I'm trying to execute something like this:

exec perl -i -pe 's/\015/\012/g' '${file}'

in my expect script and I get:

error "invalid command name \"perl\".

however, if I run

perl -i -pe 's/\015/\012/g' "/Users/Shared/menu-items.txt"

directly in my terminal, it runs fine. I'm an exec/shell novice, so hopefully this is an easy one. Any help is much appreciated!

Try without exec in script.

I removed exec, so the line is now:

perl -i -pe 's/\015/\012/g' "/Users/Shared/menu-items.txt"

error "invalid command name \"perl\"

while executing...

execute the below command

 
which perl

and you will get a output like /bin/perl or something....

then replce the perl with the absolute path of "which perl" output

5 
/usr/bin/perl -i -pe 's/\015/\012/g' "/Users/Shared/menu-items.txt"

error "invalid command name \"/usr/bin/perl\"
    while executing
\"/usr/bin/perl -i -pe 's/\\015/\\012/g' \"/Users/Shared/menu-items.txt\"\"

Perhaps the error is too vague. Maybe it doesn't like something else about the syntax (even though that one line runs fine in the terminal)
