As I find this find statement very handy but because I often
forget commands I use seldom, I have put this useful thing
into a useable script.
Maybe a silly idea to execute a shell script invoking perl
from a perlscript, but the target "Get it working" is reached :-)
#!/usr/bin/perl -w
#
# replace_in_tree replaces stringx by stringy in files from current di
+rectory
# recursiveley and backups the original files to *.bak like
# find . -type f | xargs -n 255 perl -pi.bak -e 's/string x/string y/g
+'
# does.

use strict;
sub usage {
print <<EOF;
usage:
replace_in_tree <to_be_replaced> <replacement> <filematcher>
replaces the string "to_be_replaced" with "replacement"
from the current directory downwards the filetree
in files matching filematcher, e.g. "*" or "*.html"
example:
replace_in_tree "Author: Bill Gates" "Author: Larry Wall" *.html
EOF
}
sub exec_replace {
open(GUN,"find . -name \"$ARGV[2]\" -type f | xargs -n 255 perl -pi.ba
+k -e 's/$ARGV[0]/$ARGV[1]/g'|")|| die "can't execute shell commands:$
+!\n";
close(GUN)|| warn "couldn't close shell:$!\n";
}
if (not $ARGV[2]) {
usage;
exit;
}
else {
exec_replace
}
exit;

there are no silly questions

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
