I have a file with a list of users.Some of the user names are like this:
ct002345
ct000123
ma005678
ma009876
mb000867
mb002412
sa000100
sb000003
sg000072
I need to extract just the number(there is 00 before each number and I
want it too) of "ct , ma , mb"(no "sa , ecc.")and all the other users
that are in the list:
example
abelar --> abelar
aci09 --> aci09
ct001234 --> 001234
ma000234 --> 000234
sg000072 --> nothing
This is the first step.Then I need to make a new file with every normal
name and for each number extacted the three possibilities(ct , ma , mb)
example
abelar --> abelar
001234 --> ct001234
ma001234
mb001234
I'm trying from a week but pattern matching is not so simple for
me.Please help me.Thanks
