lcksum(1) User Commands lcksum(1)NAMElcksum - verifies a transcript's checksums and file sizes
SYNOPSISlcksum [-%AiIqV] [ -D path ] [ -n [ -a ]] [ -P prefix ] -c checksum
transcript ...
DESCRIPTIONlcksum verifies and updates the checksums and file sizes of the tran‐
script transcript line-by-line. If more than one transcript is passed
to lcksum, all transcripts will be verified and updated. lcksum com‐
pares the checksum and file size listed in transcript to that of the
file in the file system. Files must be located in file directory asso‐
ciated with transcript. With the -n option lcksum verifies but does
not modify transcript.
If there is a difference in either the checksum or file size, the tran‐
script line is updated using the checksum, file size and modification
time of the actual file.
In update mode, lcksum may modify the file sizes and/or checksums in
transcript, so the user must have write access to transcript. If an
error occurs during an update of transcript, lcksum removes the tempo‐
rary copy of transcript that it created and exits with a status of 2.
lcksum also verifies that transcript is sorted in depth first order.
With the -P option, lcksum will only verify transcript lines with paths
starting with prefix.
OPTIONS
-% progress output.
-a continue checking on error. Requires -n option.
-A verify AppleSingle headers.
-c checksum enables checksuming.
-D path specifies the radmind working directory, by default
/var/radmind
-i force line buffering.
-I be case insensitive when compairing paths.
-n verify but do not modify transcript.
-P prefix only verify transcript lines that begin with prefix.
-q suppress all messages.
-V displays the version of lcksum and a list of sup‐
ported checksumming algorithms in descending order
of preference and then exits.
EXIT STATUS
The following exit values are returned:
0 Transcript was verified.
1 Differences were found.
>1 An error occurred.
