edquota - edit user quotas
The quotas may then be modified, new quotas added, etc. Setting a quota to zero indicates that no quota should be imposed. Setting a hard limit to one indicates that no allocations should be permitted. Setting a soft limit to one with a hard limit of zero indicates that allocations should be permitted only on a temporary basis (see -t below). The current usage information in the file is for informational purposes; only the hard and soft limits can be changed.
On leaving the editor, reads the temporary file and modifies the binary quota files to reflect the changes made.
If the -p option is specified, will duplicate the quotas of the prototypical user specified for each user specified. This is the normal mechanism used to initialize quotas for groups of users. If the user given to assign quotas to is a numerical uid range (e.g. 1000-2000), then will duplicate the quotas of the prototypical user for each uid in the range specified. This allows for easy setup of default quotas for a group of users. The uids in question do not have to be currently assigned in /etc/passwd
If one or more -e fspath [: bslim [: bhlim [: islim [: ihlim ] ] ] ] options are specified, will non-interactively set quotas defined by bslim , bhlim , islim and ihlim on each particular file system referenced by fspath Here bslim is the soft limit on the number of blocks, bhlim is the hard limit on the number of blocks, islim is the soft limit on the number of files, and ihlim is the hard limit on the number of files. If any of the bslim , bhlim , islim and ihlim values is omitted, it is assumed to be zero, therefore indicating that no particular quota should be imposed.
If invoked with the -f option, will read and modify quotas on the file system specified by fspath only. The fspath argument may be either a special device or a file system mount point. The primary purpose of this option is to set the scope for the -p option, which would overwrite quota records on every file system with quotas otherwise.
If the -g flag is specified, is invoked to edit the quotas of one or more groups specified on the command line. The -p flag can be specified in conjunction with the -g flag to specify a prototypical group to be duplicated among the listed set of groups. Similarly, -e flag can be specified in conjunction with the -g flag to non-interactively set-up quotas on the listed set of groups.
Users are permitted to exceed their soft limits for a grace period that may be specified per file system. Once the grace period has expired, the soft limit is enforced as a hard limit. The default grace period for a file system is specified in In ufs/ufs/quota.h . The -t flag can be used to change the grace period. By default, or when invoked with the -u flag, the grace period is set for all the file systems with user quotas specified in /etc/fstab When invoked with the -g flag the grace period is set for all the file systems with group quotas specified in /etc/fstab The grace period may be specified in days, hours, minutes, or seconds. Setting a grace period to zero indicates that the default grace period should be imposed. Setting a grace period to one second indicates that no grace period should be granted. Quotas must be turned off for the file system and then turned back on for the new grace period to take effect.
Only the super-user may edit quotas.
