Using awk to replace strings
Hi.. I have a file that has the following content :
Code:
abc 213 24 213
pqr 456#34 678
xyz 213 45%213

i need to write an awk script that will replace the second 213 in all the lines, if it is present. The IFS can not be specified and can be random.

The number of lines in the file and the columns in each line are not fixed.

Please suggest a solution. Thanks!
