chtab.8¶

NAME¶

chtab - Add, delete or update rows in the database tables.

SYNOPSIS¶

chtab [-h | --help]

chtab [-v | --version]

chtab keycolname=keyvalue[,keycolname=keyvalue,…] tablename.colname=newvalue [tablename.colname=newvalue …]

chtab keycolname=keyvalue[,keycolname=keyvalue,…] tablename.colname+=newvalue [tablename.colname+=newvalue …]

chtab -d keycolname=keyvalue[,keycolname=keyvalue,…] tablename [tabname …]

DESCRIPTION¶

The chtab command adds, deletes or updates the attribute values in the specified table.column for the specified keyvalue. Normally, the given value will completely replace the current attribute value. But if “+=” is used instead of “=”, the specified value will be appended to the comma separated list of attributes, if it is not already there.

The chtab does not pass through xcatd, so it is not controlled by the policy mechanism.

OPTIONS¶

-h Display usage message.

-v Command Version.

-d Delete option.

RETURN VALUE¶

The command completed successfully.
An error has occurred.
