Shell Programming and Scripting

Next, write a C shell script (called ss1) with a synopsis
ss1 [-r] directory
The ss1 command takes a directory path name as its argument and applies your awk script
(aa1) separately to each of the web page files (those with .html and .htm extensions etc) in the
directory. The output from the shell script should be to the standard output. If the r option is set,
the command should run recursively over all subdirectories in the hierarchy below the directory.
To run ss1 on your own file hierarchy it should be possible to do this with the command
aa1 -r $HOME
NB you should choose a form for listing your urls in the output of aa1 so that you can run aa1
again on your output from ss1 (eg by piping the output from ss1 into aa1) to produce a summary of
all the links in all the web pages in the hierarchy. The number of times each link occurs will now
be the number of FILES in which each occurs.

Does your input file come from Windows ?

Try to modify the AWK program :

Code:

#!/bin/gawk -f
{
   if ($0 !~ /<a|<img/) next;
   link++;
   gsub(/\r+/, "");
