Remove a line from a file
Hi ,guys. I have one question:
I want to write a script which removes a line with certain string from a file, for example
The name of the file is: "passwd", the contents of it is below:
*************************
...
brownj2:x:5000:
hynesp:x:5001:
leeb:x:5002
dioxna:x:5003
...
*************************
I want to remove the line with "brownj2" from the file.
Here is my code:
user="brownj2"
sed '/^user:/'d passwd
But, this does not work
Firstly, line with "brownj2" is not removed.
Secondly, I got all the contents in passwd shown up in the terminal, which is not what I want
Can anybody help me with this?
Thank you very much for your time in advance.

slapd-passwd
SLAPD-PASSWD(5) File Formats Manual SLAPD-PASSWD(5)
NAME
slapd-passwd - /etc/passwd backend to slapd
SYNOPSIS
/etc/ldap/slapd.conf
DESCRIPTION
The PASSWD backend to slapd(8) serves up the user account information listed in the system passwd(5) file. This backend is provided for
demonstration purposes only. The DN of each entry is "uid=<username>,<suffix>". Note that non-base searches scan the the entire passwd
file, and are best suited for hosts with small passwd files.
CONFIGURATION
This slapd.conf option applies to the PASSWD backend database. That is, it must follow a "database passwd" line and come before any subse-
quent "backend" or "database" lines. Other database options are described in the slapd.conf(5) manual page.
file <filename>
Specifies an alternate passwd file to use. The default is /etc/passwd.
ACCESS CONTROL
The passwd backend does not honor any of the access control semantics described in slapd.access(5). Only read (=r) access to the entry
pseudo-attribute and to the other attribute values of the entries returned by the search operation is honored, which is performed by the
frontend.
FILES
/etc/ldap/slapd.conf
default slapd configuration file
/etc/passwd
user account information

slapd.conf(5), slapd(8), passwd(5).
