flag=0
while IFS='|' read -r line f_path p_path; do
set -f # disable globbing
# echo $line
if [[ $CHK_FILE =~ "${line}*" ]] ;# True if file name is equal to line* (literal matching).
then
flag=1
break
else
flag=0
fi
done < config .txt
if [ $flag = 1 ]
then
do this
else
do this
fi
In this case I able to make file name comparison but can’t stop to avoid when line contain username ,ip,… also I am planning to put all vales in variable for future understanding
Please do not add FONT and SIZE tags to every line in your postings (especially inside CODE tags). The constant width font used by CODE tags makes spacing and text clear in code segments, sample input, and sample output. Overriding the CODE tag font and reducing the size of the text makes it harder to interpret these key elements of any issues you may have.

Reason: Removed dozens of FONT and SIZE tags.

readonly
READONLY(P) POSIX Programmer's Manual READONLY(P)
NAME
readonly - set the readonly attribute for variables
SYNOPSIS
readonly name[=word]...
readonly -p
DESCRIPTION
The variables whose names are specified shall be given the readonly attribute. The values of variables with the readonly attribute cannot
be changed by subsequent assignment, nor can those variables be unset by the unset utility. If the name of a variable is followed by =
word, then the value of that variable shall be set to word.
The readonly special built-in shall support the Base Definitions volume of IEEE Std 1003.1-2001, Section 12.2, Utility Syntax Guidelines.
When -p is specified, readonly writes to the standard output the names and values of all read-only variables, in the following format:
"readonly %s=%s
", <name>, <value>
if name is set, and
"readonly %s
", <name>
if name is unset.
The shell shall format the output, including the proper use of quoting, so that it is suitable for reinput to the shell as commands that
achieve the same value and readonly attribute-setting results in a shell execution environment in which:
1. Variables with values at the time they were output do not have the readonly attribute set.
2. Variables that were unset at the time they were output do not have a value at the time at which the saved output is reinput to the
shell.
When no arguments are given, the results are unspecified.
OPTIONS
See the DESCRIPTION.
OPERANDS
See the DESCRIPTION.
STDIN
Not used.
INPUT FILES
None.
ENVIRONMENT VARIABLES
None.
ASYNCHRONOUS EVENTS
Default.
STDOUT

STDERR
The standard error shall be used only for diagnostic messages.
OUTPUT FILES
None.
EXTENDED DESCRIPTION
None.
EXIT STATUS
Zero.
CONSEQUENCES OF ERRORS

The following sections are informative.
APPLICATION USAGE
None.
EXAMPLES
readonly HOME PWD
RATIONALE
Some historical shells preserve the readonly attribute across separate invocations. This volume of IEEE Std 1003.1-2001 allows this behav-
ior, but does not require it.
The -p option allows portable access to the values that can be saved and then later restored using, for example, a dot script. Also see
the RATIONALE for export for a description of the no-argument and -p output cases and a related example.
Read-only functions were considered, but they were omitted as not being historical practice or particularly useful. Furthermore, functions
must not be read-only across invocations to preclude ``spoofing'' (spoofing is the term for the practice of creating a program that acts
like a well-known utility with the intent of subverting the real intent of the user) of administrative or security-relevant (or security-
conscious) shell scripts.
FUTURE DIRECTIONS
None.
