That is a function of the shell and the command line editor you are working in/with. I work in KSH so I set my EDITOR environmental variable to <B>vi</B> and have the entire range of vi search and replace on the command line. This is the same as all the vi commands in a file. For example, to move forward a line: <ESC>j ; backwards: <ESC> k. To search for a command: <ESC>/string . This is very powerful and fast (much more powerful than DOS, BTW).

Other use EMACS as the command line editor.

Also, differnet shells have builtins that do not require using a command line editor. For me, I could not imagine not using vi or emacs on the command line. The power is amazing.

vipw(8) 						      System Manager's Manual							   vipw(8)

NAME
vipw - Edits the /etc/passwd file SYNOPSIS
/usr/sbin/vipw DESCRIPTION
You use the vipw command to edit the /etc/passwd file with the editor defined in the EDITOR environment variable. If the variable is not set, the default editor is vi. The vipw command performs basic consistency checks on the edited file. If a hashed indexed passwd existed previously, the vipw command uses the mkpasswd command to create recreate it. The command must not be used on systems that use extended security attributes since it cannot set or change them. You must be root to run this command. Only root and security administrators should have execute access to this command. Since the vipw command cannot effectively change all the attributes of users, it should not be used in a secure environment. The vipw command accesses the following files, and requires the listed permissions: ------------------------------ Permissions File ------------------------------ rw /etc/passwd rw /etc/passwd.pag rw /etc/passwd.dir rw /etc/ptmp rw /etc/ptmp.pag rw /etc/ptmp.dir ------------------------------ EXAMPLE
To edit the /etc/passwd file, type the following command and add the required line entry: vipw FILES
Specifies the command path RELATED INFORMATION
Commands: passwd(1), passwd(4), adduser(8), mkpasswd(8) delim off vipw(8)
