Re: Multiple files editing

The carbonbased lifeform GT inspired alt.os.linux with:
[..]
So, from a bat file containing :

call something

I wish to replace it by :

echo (options) something >> logfile
call something
echo (options) out of something >> logfile


Something like this?
#v+
#!/usr/bin/env python

import re, os, sys

f1 = open(os.argv[1],rb)
f2 = open(os.argv[2],wb)
call = re.compile('^call\s+(.*)')
preCall = "echo (options) something >> logfile"
postCall = "echo (options) out of something >> logfile"

for line in f1:
if call.match(line):
f2.write(preCall)
f2.write(line)
f2.write(postCall)
else:
f2.write(line)

f1.close()
f2.close()
#v-

I'm sure a oneliner perl/awk/bash can be made, but I like my scripts
readable, and I don't care much for a 50 bytes saving in diskspace..

If there was a way to log call errors as well, life would be nice.

You can at least test if the called object exists before calling, but
afaik a 'call' is like an 'exec' in Unix shell, it forkes a new process,
so the parent is stopped, and therefor can not log data from the child.

It seems DOS is a little poor in terms of utilities. I could write a
fortran proggy but if there was a simpler way under linux, which is
often the case, that would be nice.

Python runs just as well in Windows, and there is also a DOS version.
