Help with Permission Denied on script with sed
I am trying to develop a script to replace a lowercase URLs with an upper case URLs in HTM files.

Basically.. replace href="somelowercaseurl" with href="SOMEUPPERCASEURL". In place.

the href's are not located in any specific position in the file.

Here is my shell script :

Code:
export PATH=$PATH
if [ $# -eq 0 ];
then
 echo "Syntax: hreftoupper [Dir needed.. In upper case]"
 exit 1
fi
for f in ./$1/*.HTM
do
echo "processing $f"
sed -ir `s/href=\"[^\"]*\"/\U\1/g` `$f`
done
echo "done"

..

I am getting permission denied on the HTML file. From the prompt I can VI the file though so I know I have permission. I assume something is wrong with the script above.. any help would be appreciated.

You are putting $f in ` ` backticks.

This attempts to execute the HTML file, as if it were a script. Since it's not set executable, it gives you permission denied. Use double quotes " " instead of backticks.

You are also putting your regex in backticks. This attempts to execute it, and will complain 'no such file or directory'. Put it in single quotes ' '.

Wherever you have a backtick ` it should be a different type of quote character. Single quotes round the sed string and double quotes round the filename.
Code:
sed -ir 's/href=\"[^\"]*\"/\U\1/g' "$f"

Ps. I can't vouch for the actual sed command, only the basic syntax.

Thanks Methyl... problem now is it seems to think the first char of the filename in $f is a command:
Error :
Code:
./testtoupper.sh: line 11: s/href="[^"]*"/U1/g: No such file or directory
sed: -e expression #1, char 1: unknown command: `A'

Sorry Corona688.. I missed your reply before Methol, thanks for your help... I am getting a new error
Code:
sed: -e expression #1, char 24: invalid reference \1 on `s' command's RHS

The code now

Code:
for f in $1/*.HTM
do
echo "processing $f"
sed -ir 's/href=\"[^\"]*\"/\U\1/g' "$f"
done

You have no \( \) on the left hand side, so nothing inside to reference with \1 there.

Thanks Corona688.. Are you saying I need to do something like this?:

Code:
sed -ir 's/\(href=\"[^\"]*\"\)/\U\1/g' "$f"

I tried it this way above and got the following error message

sed: -e expression #1, char 23: unknown option to `s'

EDIT... no typo on my end.. IT WORKED!... thanks
