How to Replace the value of a column using awk command?
Hi
cat test.txt

Code:
H|123|341|567|asfg
D|dfg|trtyy|errt
D|ert|frty|wer

Here I need to replace the third column value with 100 of the first record only and while printing I need to print the full file content also..I am expecting a result like this

Code:
H|123|100|567|asfg
D|dfg|trtyy|errt
D|ert|frty|wer

Can some one please help on this

Code:
