pwck(1M)pwck(1M)NAMEpwck - password file checker
SYNOPSISpwck [[-p] file]
DESCRIPTIONpwck scans the password file and notes any inconsistencies. The checks
include validation of: the number of fields, login name, user ID, group
ID, and whether the login directory and the program-to-use-as-Shell
exist. The default password file is /etc/passwd.
pwck has the ability to parse YP entries in the password file.
The -p option prevents checking of the login directory and shell fields,
useful for NIS administrators in checking the yppasswd file, where each
login directory is not usually locally available.
FILES
/etc/passwd
SEE ALSOpasswd(4).
