awk shebang不起作用

Question

I have a simple awk program:

#!/usr/bin/awk -f
BEGIN {print "work already!"}

If I run it as:

awk -f panic

on the (osx) terminal it works. But it fails if I try running it as a script:

. panic
-bash: BEGIN: command not found

I checked the location of awk using which awk and it is indeed located at /usr/bin/awk . Any ideas why it isn't working?

Answer 1

Run it as ./panic , not . panic . panic , as the latter is the same as running source panic , which won't do what you want. See man source

Answer 2

To run a file as a script you must type:

./<script>

Edit :

As pointed by William Pursell, . is not an alias for source , but the exact contrary.

. is not an alias for source. . is the sh standard command for running another script inside the current shell. source is a command that originated in csh and was adopted by many sh clones as an alias for .. If source is to be viewed as anything but an abomination, it is an alias for ., not the other way around.
