column handling in awk
Dear Scripting experts,
I have a problem which i cannot get my head around and wondered if anyone can help me. I have two files "file1" and "file2" and i want to replace column one from file 1 with column one with file2.(where file two has many columns). see example.. ive tried to use cut and paste but got myslef in a mess... file1 file2 1 9 66 8 A 2 8 3 9 B 3 66 4 25 C 4 66 2 6 D 7 4 3 3 E 5 4 5 45 F Output:- 1 66 8 A 2 3 9 B 3 4 25 C 4 2 6 D 7 3 3 E 5 5 45 F Is there an easy way i can do this in awk? ideally i would like to have a one liner which i could invoke using the system command in a perl script. Thanks Mish |
