# gfcksum(1)

print checksum

## NAME

gfcksum - print checksum

## SYNOPSIS

**gfcksum** \[-rl\] \[-T \| -t\] *path*...

**gfcksum** -c \[-rlv\] \[-h *host*\] *path*...

## DESCRIPTION

**gfcksum** prints checksum of specified files. When -r option is specified, it prints checksum of subentries in the specified directories recursively.

When -t option is specified, only checksum type which is currently set to the file is printed. When -T option is specified, which checksum type will be calculated is printed.

When the -c option is specified, it calculates the checksum of the specified files, and compares it with the checksum stored in the metadata. The -h option specifies the location of the file replica to be calculated. With the -v option, the verbose information including modification time of the file replica is displayed.

If the -l option is present, **gfcksum** displays a path for each file. By default, gfcksum shows its basename only.
