I have this in my .profile:
stty erase `tput kbs`
which sets erase to ^H for a vt and ^? for an xterm.
This has been fine up until now on all systems whether I login using a vt terminal emulator or an xterm.
On this new system though, if I log in directly using an xterm, backspace doesn't... (1 Reply)

amstar
AMSTAR(8) System Administration Commands AMSTAR(8)NAME
amstar - Amanda Application to interface with star
DESCRIPTION
Amstar is an Amanda Application API script. It should not be run by users directly. It uses star to backup and restore data.
The diskdevice in the disklist (DLE) must be the directory to backup.
INCLUDE - EXCLUDE
amstar doesn't support include. Both 'exclude list' and 'exclude file' are supported. There is a maximum of 100 patterns (limit of star).
Moving directories into and out of directories on the exclude list causes incremental backups to not contain the files in the moved
directories until the next full backup unless the moved files are modified after the move.
PROPERTIES
This section lists the properties that control amstar's functionality. See amanda-applications(7) for information on application properties
and how they are configured.
ACL
If "YES" (the default), amstar will store files acl by passing the -acl argument to star. If "NO", then the -acl option is not given to
star, and it will not try to backup the acl.
COMMAND-OPTIONS
If set, theses options are passed asis to star. Each option must be a different value of the property. Some option can break how amanda
do backup, use it with care.
Use:
property "COMMAND-OPTIONS" "--foo" "bar"
Do not use:
property "COMMAND-OPTIONS" "--foo bar"
DIRECTORY
If set, gnutar will backup from that directory instead of the diskdevice set by the DLE. On restore, the data is restore in that
directpory instead of the current working directory.
ONE-FILE-SYSTEM
The default is "YES". This property is deprecated and the default value can't be changed. star requires it when it works in dump mode.
This corresponds to the -xdev option of star.
SPARSE
If "YES" (the default), star will store sparse files efficiently. If "NO", then the -sparse option is not given to star, and it will
not try to detect sparse files.
STAR-DLE-TARDUMP
If "YES", amstar will use a different tardump file for each DLE. The default is "NO". This property is needed with older versions of
star doing many dumps in parallel, because of a race condition in updating the tardump file.
STAR-PATH
The path to the star binary. The default is set when Amanda is built by the --with-star configure option.
STAR-TARDUMP
The directory where star stores the database it uses to generate incremental dumps. The default is /etc/tardumps.
NORMAL
List all regex (POSIX Extended Regular Expression syntax) that are normal output from star. These output are in the "FAILED DUMP
DETAILS" section of the email report if the dump result is STRANGE or FAILED. Default values:
"^could not open conf file"
"^Type of this level "
"^Date of this level "
"^Date of last level "
"^Dump record level "
"^Throughput"
"^.*is sparse$"
"^star: dumped [0-9][0-9]* (tar )?files"
"^.*The following problems occurred during .* processing.*$"
"^.*Processed all possible files, despite earlier errors.*$"
"^.*not written due to problems during backup.*$"
To treat one of these default patterns differently, specify it explicitly in a different property.
IGNORE
List all regex (POSIX Extended Regular Expression syntax) that amanda ignore. These output are never in the email report.
STRANGE
List all regex (POSIX Extended Regular Expression syntax) that are strange output from star. All star output that doesn't match a
normal or ignore regex are strange by default. The result of the dump is STRANGE if star produce a strange output. These output are in
the "FAILED DUMP DETAILS" section of the email report.
"^Perform a level 0 dump first.*$"
To treat one of these default patterns differently, specify it explicitly in a different property.
