Can someone help me with the code wherein there is a file f1.txt with different column and 34 column have expiry date and I need to get that and compare with system date and if expiry date is <system date remove those rows and other rows should be moved to new file f2.txt .
I don't want to delete f1.txt

Could you please elaborate a little:

  • What is your operating system, its version, which shell do you use, which version is it, .... ?
  • can you post (within CODE-tags!) a sample of this f1.txt file?
  • what exactly do you mean by "system date"? The output of the date command on the system?

I hope this helps.
