#!/usr/bin/perl
$a = shift @ARGV;
system("sed -i 's/" . shift @ARGV . '/' . shift @ARGV . "/g' $a");

Dammit! That'll teach me not to test my scripts before posting! Order of
precendence...

#!/usr/bin/perl
$a = shift @ARGV;
system("sed -i 's/" . (shift @ARGV) . '/' . (shift @ARGV) . "/g' $a");

And here's a shorter one...

#!/usr/bin/perl
system("sed -i 's/".$ARGV[++$a].'/'.$ARGV[++$a]."/g' ".$ARGV[$b]);

English language, it's richness and complete lack of logic!

And its wayward apostrophes! :-D

 

[Matt Probert]

Is two lines (excluding shebang) too many? I can do it in one if I'm
allowed to change the order of the arguments to STRING, REPLACEMENT,
FILESPEC.

#!/usr/bin/perl
$a = shift @ARGV;
system("sed -i 's/" . shift @ARGV . '/' . shift @ARGV . "/g' $a");

(Very dirty. Won't work for some STRINGs -- anything that has a special
meaning in a regexp.)

Will that work under Windows? Looks to me like it's calling an
external program - 'sed'.

Touche!

I always think (well sometimes) that "its" should have an
apostrophe...I know, I know...

'sed' is available for Windows.

Me too, because you were talking about the richness belonging to "it". So
it should be "it's" richness!

I had "it's" (in the possessive sense we are discussing here) on a website.
Some stuffy guy emailed to point it out, which I then changed. It happens!

That's exactly my argument. I'm not a linguist, I don't trace the
roots of words to argue their correctness, I'm a writer.

What can I say? English is a stupid language.

I'd be the stuffy guy who'd notice it, and laugh about it with his
friends, although I wouldn't email you about it. *sigh* I'm such a nerd.

Why? No other possessive pronoun does:
his, hers, ours, its

By contrast, contractions always use an apostrophe:
didn't, won't, shouldn't, it's
