Re: oneliner: autorun script when I save it in the editor

Nice one! I modified it a bit to compile and run a C program:

perl -E 'while(-f $ARGV[1]){ $now=(stat(_))[9]; system("@ARGV"), print
+ "-" x 80, "\n" if ($now-$prev); $prev=$now; sleep 1 }' gcc a.c \&\& 
+./a.out

I think every Unix/Linux sysadmin should know shell (sh or bash) plus one of Perl, Ruby, Python. It doesn't matter which. -- Tom Limoncelli (http://everythingsysadmin.com/2012/06/salang.html)

The delimiter line is a nice touch... And using `$ARGV[1]` instead of `$ARGV[0]` is good thinking! I now use it more as a perl -wc thingy... so I save, and know if the added code is syntax-error free (of course, most of the times it is still buggy)	[reply] [d/l] [select]
