I am a newbie to Unix, I am using vi editor. I was able to print output to the screen using simple scripts. But when I tried a midlevel script I don't see anything on the screen and Cursor is just blinking when I type ./test11 filename. I have used chmod 755 also, but of no use. Any help would be appreciated. Here is my script:
The 2nd line of the file has filename, filesize and record count. I want to capture in a variable since I need to work on it for different purpose and display seperately on the screen.
1. There is no input file to the awk command. The script won't figure out that you wanted to run the awk statement against the file you specified on the command line, so the awk command is hanging waiting for input.
2. You are not setting variables in the script by setting them in awk.
3. You don't need to traverse the whole file if you only want the second line, you could exit() after processing the line.
An example of what might work ( keeping the awk )...untested
The editor you use has no bearing on the script -- unless you are using a Microsoft editor which puts both a carriage return and a linefeed at the end of each line. (Unix systems only use a linfeed.)

Code:
#!/bin/ksh
awk 'NR==2 {
To read the second line of a file, it is quicker to use the shell than an external program:
Code:
{
read
IFS= read -r line
} < "$FILE"
To split the line into its constituent parts, use shell parameter expansion:
