Check for length which exceeds specified length in a line
Hi,
I have a issue, I need to loop through a comma delimited file and check for the length which exceeds specified length , if Yes truncate the string.
But my problem is , I do not have to check for all the fields and the field lenght is not same for all the fields.
For ex:
Say my line
ahjdh,dfhkajhdf,adhklf,eiour
say I need to check length only for 2nd and 4th and max length for 2nd is 6 and max length for 4th field is 4.
Can somebody please help me.
I was trying with AWK , but couldn't move forward with it , please let me know if my logic is correct.
Thank you guys , checking the length and print works , but I also need to print the field name along with it . But somehow I am not able to print the field.
Can you please tell if we can print the array value.
