No. It's used as

counter

YES, be aware of the strike through.
[QUOTE]However I cannot understand why we need counter+=NF in this case, as NF should be 16. Can you please explain this logic? [QUOTE]
The
counter in fact is a pointer into the file, starting at the zeroth byte, then at the 16th, etc. Thus adding the line length (better: line's byte count) keeps the pointer pointing to the correct file position.

Can we use something else to accomplish this (i.e for loop).
What?

convertquota
CONVERTQUOTA(8) System Manager's Manual CONVERTQUOTA(8)
NAME
convertquota - convert quota from old file format to new one
SYNOPSIS
convertquota [ -ug ] [ -e | -f ] filesystem
DESCRIPTION
convertquota converts old quota files quota.user and quota.group to files aquota.user and aquota.group in new format currently used by
2.4.0-ac? and newer or by SuSE or Red Hat Linux 2.4 kernels on filesystem.
New file format allows using quotas for 32-bit uids / gids, setting quotas for root, accounting used space in bytes (and so allowing use of
quotas in ReiserFS) and it is also architecture independent. This format introduces Radix Tree (a simple form of tree structure) to quota
file.
OPTIONS
-u, --user
convert user quota file. This is the default.
-g, --group
convert group quota file.
-f, --convert-format
convert from old file format to new one. This is the default.
-e, --convert-endian
convert new file format from big endian to little endian.
-V, --version
print version information.
FILES
aquota.user new user quota file
aquota.group new group quota file
SEE ALSO
quota(1), setquota(8), edquota(8), quotacheck(8), quotaon(8), repquota(8)
