Read the record from a text file
Hi

I want to read one row record from a text file.

For eg: I have Sample.txt file with one row of record like

123456768

I want to get the above value from the file and assign it to a variable in my script. Please guide me how to proceed.

Thanks,
Soll

exec 3<> file  #open file handle 3
read line <&3 #read one line
echo $line 
3<&- #close file descriptor

Code:
read line < file
