pg_restore and pgadmin3

Hi,


I normally use pgadmin3 for backups and restorations. But sometimes, I only have terminal access to certain servers. When I try to restore a backup made with pgadmin3,

pg_restore -dmydb --disable-triggers mydb.backup

i get

pg_restore: [archiver] could not open input file: Permission denied.

How do i restore the backup file correctly?


Thanks
