Re: Can anyone make this shorter?

Arr... Cheesy likes golfing...

#23456789_123456789_123456789_123456789_12345678 (48)
perl -pi.bak -e's/(xyz\s*=\s*)(\d+)/$1.($2+1)/e' test.data

Update: Anything maverick can do, I can do better... (j/k):

perl -pi.bak -e'/^xyz\b/&&s/\d+$/$&+1/e' (40)

As long as your file is formatted correctly, that should avoid any trip-ups.

And a slice of -pie: Check out perlrun for all your command-line option needs. :-)

Excuse me whilst I bow and kiss your cycle clips. I would really love to know how that line does what it does. I get the regex stuff, but it's the perl -pi.bak -e ..... test.data bit I have no clue about. Would any monk be kind enough to enlighten me? § George Sherston	[reply]
