In Unix i am using the following command to read one line from a file and echo it but this does not work. I have used it before (in another project) and it had worked there

Code: 
cat /usr/tmp/abc.txt | read errcode
echo $errcode

Is there any other way i can read from this file which will have only one line.
 
then may be this work out for you

Code: 
errcode=`cat /usr/tmp/abc.txt`

echo $errcode

Code: 
[kekerode@m-net ~]$ cat abc.txt

skjdajkdakjdasjkdas

[kekerode@m-net ~]$ echo $err123

[kekerode@m-net ~]$ err123=`cat abc.txt`

[kekerode@m-net ~]$ echo $err123

skjdajkdakjdasjkdas

[kekerode@m-net ~]$
