In your code, you'd have to break out of the loop when the test passes. Or, do the test directly in while, then read at the end of loop:
Code:
#!/bin/bash
echo "Please enter the source system: "
read SYSTEM_NAME
while ! [[ $SYSTEM_NAME == "L1" || $SYSTEM_NAME == "L2" || $SYSTEM_NAME == "P1" || $SYSTEM_NAME == "P2" ]] ; do
echo "\nPlease enter the source system as L1 L2 P1 P2"
read SYSTEM_NAME
done
echo "Making $SYSTEM_NAME as source system for particular script"
#continue with $SYSTEM_NAME
Mirni.
the code is on the lines 30-35 ,and while running it throws error on different piece of code.
./switch_dist.sh: syntax error at line 41: `(' unexpected
And, at 41st line, i have following statement in place. Looks like while is not working with parenthesis.
41 echo "\nDo you wish to continue...(y/n): \c"

I am trying to create a shell (ksh) which has two "read" commands, one which reads a line from a file and another which is inside a loop that reads user input from a keyboard.

LEARN ABOUT SUNOS
echo
echo(1B) SunOS/BSD Compatibility Package Commands echo(1B)NAME
echo - echo arguments to standard output
SYNOPSIS
/usr/ucb/echo [-n] [argument]
DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output.
echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi-
ronment variables.
For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows:
o echo your current-working-directory's full pathname
o pipe the output through tr to translate the path's embedded slash-characters into space-characters
o pipe that output through wc -w for a count of the names in your path.
example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w"
See tr(1) and wc(1) for their functionality.
The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if
the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape
characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's
echo() also understands a as the audible bell character; however, these commands do not have an -n option.
OPTIONS -n Do not add the NEWLINE to the output.
