if, sed or awk with conditions
I do not know how to do this unless I use a bunch of if statements. I need a script to replace numbers in each record in a file. I am really getting tangled in this web.
If a fieldA (19 positions) is greater than 14 digits, I have to change the data (resulting fieldA is fixed 19 postions).
If there are preceding zeros. For example:
'000123456789012 ' would be changed to '123456789012 '
'001234567890123 ' would be changed to 1234567890123 '
'012345678901234 ' would be changed to 12345678901234 '
'123456789012345 ' would not be changed but would report error

I would appreciate any help or direction. Thanks.

						       TPM Management - tpm_changeownerauth

NAME

       tpm_changeownerauth - change the authorization data associated with the owner or SRK

SYNOPSIS

       tpm_changeownerauth [OPTION]

DESCRIPTION

       tpm_changeownerauth allows for changing the authorization data for the TPM owner or the TPM's Storage Root Key (via the TPM_ChangeAuthOwner
       API).  This operation prompts for current password, followed by the new password and a confirmation of the new password. The --owner option
       changes the TPM owner password and --srk option changes the TPM's SRK password. The --well-known option is used when SRK or owner passwords
       need to be changed and current owner password is a secret of zeros, --set-well-known option changes current password to a secret of zeros,
       both options do not work by themselves, they must be used with --owner and --srk options to indicate which of these passwords will be
       changed.
