Does anyone know of a way to mimic the up arrow/down arrow type bash behavior within a shell script?
Say I have a scripted menu, and would like to be able to up arrow to bring up the last X number of lines of user input?
Thanks to anybody with a suggestion. :) (0 Replies)

grpck
pwck(8) System Manager's Manual pwck(8)NAME
pwck, grpck - Checks the password and group files for inconsistencies
SYNOPSIS
pwck [-admNs] [file]
grpck [-mNp] [file]
FLAGS
Causes both pwck and grpck to additionally check the NIS database entries using the same consistency tests. Users that are defined in the
local password or group file without the "+" at the start of the name field are flagged as duplicate entries.
pwck
Inhibits the running of the /tcb/bin/authck -p command on a system running Enhanced Security. Prevents pwck from checking for the presence
of the user's login directory. Directs pwck to check for mixed case usernames. Causes pwck to check for the presence of the optional
shell field for each entry.
grck
If there are no members, causes grpck to display a message indicating the listed group has no members. Directs grpck to not check for a
users' existence in the password database (local or NIS).
DESCRIPTION
The pwck command scans the /etc/passwd file, or the named file, and writes to standard out any inconsistencies. The scan checks the number
of fields, login name, user ID, group ID, and existence of a login directory and optional program name.
The grpck command scans the /etc/group file, or the named file, and writes to standard out any inconsistencies. The scan checks the number
of fields, group name, group ID, and whether all login names appear in the password file.
EXAMPLES
To verify the password information in the /etc/passwd file for consistency, enter: pwck
To verify the password information in the /etc/passwd file and the NIS database for consistency without checking each users login directory
validity, enter: pwck -Nd
To verify the group information in the /etc/group file and the NIS database for consistency, enter: grpck -N
FILES
Specifies the command path Specifies the command path Contains user information Contains group information
