NAME

snapshot-compare - compare two snapshots of a directory tree

SYNOPSIS

snapshot-compare <snapshot-1> <snapshot-2> [:strip=N] [:strip1=N] [:strip2=N]

DESCRIPTION

snapshot-compare

will load the two directory snapshot databases, strip a number of slashes from the pathnames of the files in the databases, then generate a report describing files which are in one snapshot but not the other, and also what files which have different MD5 checksums between snapshots.

The following example shows that the file foo.bar is contained exclusively in the x.after snapshot, and the snapshot-compare.1 file is different between snapshots.

bosa00> ./snapshot-compare x.before x.after
; loading x.before
; done 227 files
; loading x.after
; done 229 files
; x.after /moby/src/kit/foo.bar
diff /moby/src/kit/snapshot-compare.1

The effect of the strip parameter is demonstrated in this example:

bosa00> ./snapshot-compare x.before x.after :strip=3
; loading x.before
; done 227 files
; loading x.after
; done 229 files
; strip 3 levels of / from x.before
; strip 3 levels of / from x.after
; x.after kit/foo.bar
diff kit/snapshot-compare.1

EXIT STATUS

Errors result in a non-zero exit status.
