Shell Programming and Scripting

Hello all ; )

I'got a file1 with a lot of emails like :

Code:

fistname.lastname@domaine1.com

And another file2 with emails like

Code:

fistname.lastname@domaine2.ct.net

I need a shell script that will read each line from the file1 and try to find if in file2 the

Code:

fistname.lastname

exist.

If yes, the script will have to replace on the file1 the

Code:

@domaine1.com

by

Code:

@domaine2.ct.net

If not do nothing.

Thanks a lot for your help

ex :
File1

Code:

az.et@qsdf.com
sdf.zet@qsdf.com

File2

Code:

az.et@wxc.cc.net

at the end of the script only the first line on file1 will be updated :

New file1 will look like this :

Code:

az.et@wxc.cc.net
sdf.zet@qsdf.com

Becarefull the script sould not be case sensitive as some adresses may be on lower or upper case.

Hi try:

Code:

awk '{i=tolower($1)} NR==FNR{A[i]=$2; next} i in A{$2=A[i]}1' FS=@ OFS=@ file2 file1
