Reading of variable in a single line command
Hi All,
Below is a sample command that I can run without any problem in the command line.
Command Line
HTML Code:
dtToday=`date +%Y%m%d`; ls -ltr ./filename_${dtToday}.txt
-rw-r--r-- 1 monuser oinstall 0 Jan 18 11:02 ./filename_20130118.txt
But once I put that command line in file (list.txt) and read from it, an error occurs. Pls. see below the code:
HTML Code:
cat ./list.txt|while read xLine
do
echo "`echo $xLine | awk -F \"|\" '{print $2}'`"
echo "========="
`echo $xLine | awk -F "|" '{print $2}'`
done
==========
[B]Result:[/B]
dtToday=`date +%Y%m%d`; ls -ltr ./filename_${dtToday}.txt
=========
./j.sh: line 6: dtToday=`date: command not found
The list.txt contains the line below:
HTML Code:
SomeText|dtToday=`date +%Y%m%d`; ls -ltr ./filename_${dtToday}.txt
Need help badly to resolve this issue. Thanks in advance.
