restic forget doesn't respect $RESTIC_HOST #5325
Description
Output of restic version
restic 0.18.0 compiled with go1.24.1 on darwin/arm64
What backend/service did you use to store the repository?
Backblaze B2.
Problem description / Steps to reproduce
The manual for restic forget says:
--host=[] only consider snapshots for this host (can be specified multiple times) (default: **$RESTIC_HOST)**
Expected behavior
If I set the environment variable $RESTIC_HOST then restic forget should only forget snapshots with that host.
Actual behavior:
restic forget forgets snapshots with other hosts:
$ echo $RESTIC_HOST
Four Sunstone
$ restic forget --dry-run --keep-last 1
repository *** opened (version 2, compression level auto)
Applying Policy: keep 1 latest snapshots
keep 1 snapshots:
...
remove 19 snapshots:
...
$
(The 19 snapshots that it removes are a bunch of snapshots with hosts other than Four Sunstone.)
If I add the command line argument --host "$RESTIC_HOST" then I do get the behaviour I expect:
$ restic forget --dry-run --keep-last 1 --host "$RESTIC_HOST"
repository *** opened (version 2, compression level auto)
Applying Policy: keep 1 latest snapshots
keep 1 snapshots:
...
