How to know which pages don't have...?
Hi & good day UNIX / Linux folks,

Some of my > 700 pages don't have this counter:

Code:
 <!--#exec cgi="/cgi-bin/counter"-->

How would one use find (?!) to know which pages _don't have_ this counter, or - alternatively - which don't have the string:

Code:
 exec cgi

(=bec. probably easier, "exec\ cgi")

for our *.html pages in folder chu/

Any advice welcome!

bw, Omar KN

Please get into the habit of posting what Operating System and version you have and what Shell you use.
Any clues about how to identify your files. Are they all with extension .html for example?
Based on the example provided, is this special line on it's own in a single-line file or perhaps somewhere else in each file?

They are all html files.

If you install this script in $HOME/bin/no_cgi:
Code:
#!/bin/bash
if ! grep -q "exec cgi" "$1"
then    printf 'No "exec cgi" in %s\n' "$1"
fi

and make it executable:
Code:
chmod +x $HOME/bin/no_cgi

You can then run the command:
Code:
find chu -name '*.htm*' -exec $HOME/bin/no_cgi {} \;

to get a list of html files that don't contain the string "exec cgi". (This assumes that all of your html files have names ending in .htm or .html. If you have html files with other filename suffixes, adjust the -name find primary operand as needed.)

If there aren't any subdirectories under chu, you don't need to use find. In this case, replace $HOME/bin/no_cgi with:
Code:
#!/bin/bash
for i in *.htm*
do
    if ! grep -q "exec cgi" "$i"
    then    printf 'No "exec cgi" in %s\n' "$i"
    fi
done

and then run:
Code:
cd chu
$HOME/bin/no_cgi

Hi Don ,

Thank you, I installed this script as described, and made it executable.

And it worked!

My first script, and I let it write out a little file adding:


Code:
 | cat > no_cgi.txt

What can I say, really cool stuff!

That's an unnecessarily inefficient solution. There's no need to invoke bash for each file. We can just use grep directly.

Also, the pattern used with -name, *.htm*, can match more than just .htm and .html files. *.htm? would be better, but could still match something undesirable.
Code:
find chu -type f \( -name '*.htm' -o -name '*.html' \) ! -exec grep -q 'exec cgi' {} \; -print

You don't need to pipe the results of the script into cat just to redirect the output to a file. You can do the redirection directly.
Code:
> no_cgi.txt

Congratulations on your first script. I hope you continue to enjoy the learning curve. Smilie

Interesting!

And - to shorten - if are all html files (none htm ) then:

Code:
 find chu -type f \( -name '*.html' \) ! -exec grep -q 'exec cgi' {} \; -print

ok, I just added:

Code:
  > no_cgi2.txt
