SED .htaccess script

zerocool22 · 06-04-2008, 07:47 AM

Hey im searching for a SED script that rewrites every .htaccess file from /home folders and set something in .htaccess to the ownership of the folder.

Any help/link/tips?

grtz

This is much more that just a SED script. If I understand you correctly, you will need to parse the ls -l listing, store the name of the file owner, and then write that to the file.

Can you give an example of where the info should be stored in the file---or should it just get appended?

yep thats exactly what i mean.

For example all .htaccess files in /home excist of the following line:

Quote:

AuthType Basic
AuthName "Give in Kerb 5 Username and Password Required active directory"
Require valid-user

Where Require valid-user needs to set too
Require user "fileowner"
For example Require user tom

this is what i came up so far. Buggy!

for .htaccess in /home/*
ls -l > $owner
do
sed -i "s@Require valid-user @Require user $owner@g" $.htaccess
done

OK:

In the script, do ls -l and extract the owner field to a variable (tools like awk or cut will do the extraction). Example:

owner=`ls -l filename|cut -d " " -f3`

Then use SED to parse the file and substitute the contents of the variable into the "Require" line.

No....

You can't use ">" to write to a variable (it writes to a file)

You don't want all of the ls -l, just the owner field.

The SED statement looks like you are on the right track....

Thx! so far i got:

for .htaccess in /home/*
$owner=`ls -l filename|cut -d " " -f3`
do
sed -i "s@Require valid-user @Require user $owner@g" $.htaccess
done

You don't say if it works...(but it wont)

The syntax for the "for" loop is:

for <something> ; do
<stuff>
done

Hint: First, run the individual commands on one file--to be sure that they do what you want. Then write the script.

Also, this does not look right:
for .htaccess in /home/*
This will find every file in /home and assign it to the variable ".htaccess". Is ".htaccess" an extension? If so, you need something like:
for file in /home/*.htaccess

oh ok thx, no .htaccess is just a file that restricts access for apache users. SO i mean every .htaccess file in every folder in home?? so not sure what to change it too

#!/bin/bash
for $.htaccess in /home/*;
do
$owner=`ls -l home$i|cut -d " " -f3`
sed -i "s@Require valid-user @Require user $owner@g" $.htaccess
done

In this construct:
for name in <something>

"name" is a variable to which you are assigning the result of <something>. Suppose I do "ls" to list the contents of a directory.
for name in ls
As I go thru this loop, the variable "name" is given the value of each entry in the "ls" listing.

So---I think you need:
for name in /home/*/.htaccess

Then use $name in the later statements, as required.

What texts are you using for scripting? I recommend starting with the Bash Guide for Beginners by Machtelt Garrels. It's free at http://tldp.org

yeah im using bash script at the moment. Thx for the info
I got some errors?
./sed.sh: line 1: me: command not found
./sed.sh: line 2: =: command not found
./sed.sh: line 3: syntax error near unexpected token `do'
./sed.sh: line 3: `do'

#!/bin/bash
for name in /home/*/.htaccess
$owner=`ls -l /home$i|cut -d " " -f5`
do
sed -i "s@Require valid-user @Require user $owner@g" $name
done
