Please help me in writing a script
I have to write a script for replacing a
line in a file
For Eg.
1)The file name is testfile
2) The testfile contains about 100 lines
3) I want to replace the 10th line and 20th
line in the file 4) The line is in the format as follows 10th line--setenv WORK_DIR /opt/informix/
this should be replaced with the following
new line---setenv WORK_DIR /home/informix/

multiple lines in the file Thanks in advance parthiban
