oh the power of python, I try to use it whenever possible since I hate it to be stuck with just java...
a simple program to find all files containing a space at a certain position and to rename it to the correct name needed for my system:
#!/usr/bin/python
import re, os
rxin = '.*bsksa.* _[0-9].txt'
foo = re.compile(rxin)
for fname in os.listdir(os.getcwd()):
allowed_name = re.compile(rxin).match
if allowed_name(fname):
os.rename(fname,fname.replace(' ',''))
or short, find files and replace spaces with nothing. The reg expression just filters the data.
Python looks very strange when you are not used to it.
ReplyDeleteMy perl script equivalent (sort of):
#!/usr/bin/perl
#
# Usage: rename.pl perlexpr [files]
($regexp = shift @ARGV) || die "Usage: rename.pl perlexpr [filenames]\n";
if (!@ARGV) {
@ARGV = < STDIN >;
chomp(@ARGV);
}
foreach $_ (@ARGV) {
$old_name = $_;
eval $regexp;
die $@ if $@;
rename($old_name, $_) unless $old_name eq $_;
}
now this looks even stranger :P
ReplyDeletewell I used to work so much with perl and this example convince me once more that I stay away from it. I know what it does and how it works, but it just looks so ugly :)
Ugly?? I was thinking exactly the same thing about your python example! :-)
