thanks corona,
i am not using any script, i am manually using vi to put some text in to the file and then checking for the inode number.
whatever you suggested is right but, i should not restrict the user to redirect the data from another file. user can edit the file using vi as well.

SETQUOTA(8) System Manager's Manual SETQUOTA(8)
NAME
setquota - set disk quotas
SYNOPSIS
setquota [ -rm ] [ -u | -g ] [ -F quotaformat ] name block-softlimit block-hardlimit inode-softlimit inode-hardlimit -a | filesystem...
setquota [ -rm ] [ -u | -g ] [ -F quotaformat ] [ -p protoname ] name -a | filesystem...
setquota -b [ -rm ] [ -u | -g ] [ -F quotaformat ] -a | filesystem...
setquota -t [ -u | -g ] [ -F quotaformat ] block-grace inode-grace -a | filesystem...
setquota -T [ -u | -g ] [ -F quotaformat ] name block-grace inode-grace -a | filesystem...
DESCRIPTION
setquota is a command line quota editor. The filesystem, user/group name and new quotas for this filesystem can be specified on the com-
mand line. Note that if a number is given in the place of a user/group name it is treated as an UID/GID.
-r, --remote
Edit also remote quota use rpc.rquotad on remote server to set quota. This option is available only if quota tools were compiled
with enabled support for setting quotas over RPC.
-m, --no-mixed-pathnames
Currently, pathnames of NFSv4 mountpoints are sent without leading slash in the path. rpc.rquotad uses this to recognize NFSv4
mounts and properly prepend pseudoroot of NFS filesystem to the path. If you specify this option, setquota will always send paths
with a leading slash. This can be useful for legacy reasons but be aware that quota over RPC will stop working if you are using new
rpc.rquotad.
-F, --format=quotaformat
Perform setting for specified format (ie. don't perform format autodetection). Possible format names are: vfsold Original quota
format with 16-bit UIDs / GIDs, vfsv0 Quota format with 32-bit UIDs / GIDs, 64-bit space usage, 32-bit inode usage and limits, vfsv1
Quota format with 64-bit quota limits and usage, rpc (quota over NFS), xfs (quota on XFS filesystem)
-u, --user
Set user quotas for named user. This is the default.
-g, --group
Set group quotas for named group.
-p, --prototype=protoname
Use quota settings of user or group protoname to set the quota for the named user or group.
--always-resolve
Always try to translate user / group name to uid / gid even if the name is composed of digits only.
-b, --batch
Read information to set from stdin (input format is name block-softlimit block-hardlimit inode-softlimit inode-hardlimit ). Empty
lines and lines starting with # are ignored.
-c, --continue-batch
If parsing of an input line in batch mode fails, continue with processing the next line.
-t, --edit-period
Set grace times for users/groups. Times block-grace and inode-grace are specified in seconds.
-T, --edit-times
Alter times for individual user/group when softlimit is enforced. Times block-grace and inode-grace are specified in seconds or can
be string 'unset'.
-a, --all
Go through all filesystems with quota in /etc/mtab and perform setting.
To disable a quota, set the corresponding parameter to 0. To change quotas for several filesystems, invoke once for each filesystem.
Only the super-user may edit quotas.
FILES
aquota.user or aquota.group
quota file at the filesystem root (version 2 quota, non-XFS filesystems)
quota.user or quota.group
quota file at the filesystem root (version 1 quota, non-XFS filesystems)
/etc/mtab mounted filesystem table
