Error Help with an 'easy' script

Hello guys,

Forgive me if I duplicate the post but i think i make a mistake choosing the correct forum.

I need some help to solve a little problem, I have a big file with almost 100.000 lines of data, here is an example of line:

Code:
100099C01101C00000000059399489283CREMOVISTAR_TX      010001C00000000000099069799MOVISTAR_Tx         070112114240005D070112114240005D100C00060475598801011C0C0C00100

What I need? please i need a script to change the first field (first number) from '1' to '2' ONLY when in the same line is present the word 'CREMOVISTAR_TX' (like in the example) or the word 'CREALEGRO_TX'.

Thanx and sorry for my english, I am from Ecuador

Lestat

If you have Python, here's an alternative:

Code:
#!/usr/bin/python
for line in open("file.txt"):
     if "CREMOVISTAR_TX" in line or "CREALEGRO_TX" in line:
         print "2%s" % line[1:]

sed one

Code:
sed -e '/CREMOVISTAR_TX/ s/^\(.\)\(.*\)$/2\2/g' -e '/CREALEGRO_TX/ s/^\(.\)\(.*\)$/2\2/g' testfile
