“No such file or directory” for /bin/awk on Ubuntu

Question

How can I install awk in this version of Ubuntu 11? I installed it from Ubuntu Software Center and I cannot use it.

I'm trying to run an awk script:

#!/bin/awk  
Begin  
{  
print strftime("ora %H, %M , %S");  
}

and I cannot run it because awk is not installed.

./l4p1.sh: /bin/awk: bad interpreter: No such file or directory

Answer 1

awk is not in /bin, it's in /usr/bin. To find out where you have awk, you can run either of the following:

which -a awk
type awk

Then, change your shebang line accordingly:

#!/usr/bin/awk

… or, even better:

#!/usr/bin/env awk

The latter will just use the version of awk for the current environment, and is portable across different systems that have awk installed somewhere else.
