error in bash script 'if' loop
SEND_MESSAGE=test
echo $SEND_MESSAGE
if [ $SEND_MESSAGE -eq test ]
then
echo `date` > update_dt_ccaps.lst
echo "The file transfer failed" >> update_dt_ccaps.lst
SEND_MESSAGE=false
fi
The above code is showing error in bash shell as :
./test: line 5: [: test: integer expression expected
But it was not showing any error in ksh.I am compelled to use the bash shell itself.
Would anyone please advise.
With Regards
Dileep

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.
