Hi,

edquota psh leads to
Quotas for user psh:
/datM: in use: 11656956k, limits (soft = 29360128k, hard = 31457280k)
        inodes in use: 3742, limits (soft = 10000, hard = 15000)
/datV: in use: 8k, limits (soft = 8000k, hard = 10240k)
        inodes in use: 1, limits (soft = 10000, hard = 15000)
which is fine. You can edit and save your choices

edquota -h psh:
Quotas for user psh:
/datM: in use: 11G, limits (soft = 28G, hard = 30G)
        inodes in use: 3742, limits (soft = 10k, hard = 15k)
/datV: in use: 8192, limits (soft = 8000K, hard = 10M)
        inodes in use: 1, limits (soft = 10k, hard = 15k)
------------------^^ missing prefix B
causes
edquota: /datV: in use: 8192, limits (soft = 8000K, hard = 10M): bad format

with the patch applied:
edquota -h psh leads to
Quotas for user psh:
/datM: in use: 11G, limits (soft = 28G, hard = 30G)
        inodes in use: 3742, limits (soft = 10k, hard = 15k)
/datV: in use: 8192B, limits (soft = 8000K, hard = 10M)
        inodes in use: 1, limits (soft = 10k, hard = 15k)
and the error is gone when saving changed values.


The fix is simple:
