2nd file

Code:

8573785485 <-> 343535353

i should replace value which starts at 28th column with corresponding value from second file for relation of value which starts at 88th column..

result

Code:

<25>343535353  ..... <88> 8573785485 ...

can anyone help we with this please

Please use code tags when presenting sample input, output, and code.

I cannot figure out what is actually in "1st file", what is actually in "2nd file", and what output you are trying to produce. Are the <25> and <88> and <-> present in those files???

Show us a few COMPLETE records from your two files (and give us their real names) and show us the corresponding output that should be produced from those two input files.

What operating system and shell are you using?

What have you tried to solved this problem?
