steve51184 · 01-27-2009, 11:51 AM

but again you really don't seem to understand i can't do this! some people can some can't

also i've looked at explode and can't figure it out nor do i think it's what i need :\

No, I do understand, but you're missing several points. Let me be more clear:

1. PHP is one option. I only mentioned it because YOU started the thread, by bringing up PHP. I gave you the link to the resource and example on how to do it via PHP.

2. BASH script is the second option. I gave you the commands to use (sed and awk), which have ample documentation, both through man pages and thousands of examples that can be easily found through Google.

3. If you can't do it, why do you not think the solutions given to you are what you need?

4. If you can't do it HIRE SOMEONE WHO CAN OR LET SOMEONE ELSE DO IT.

Google for "linux sed search replace". You will find lots of information with sample scripts that you can use. If that's too hard, again....HIRE SOMEONE.

getting to work now will post what i have soon

steve51184 · 01-27-2009, 12:41 PM

right now i'm getting somewhere but i'm having trouble so i'll post what i have:

this strips the "RewriteCond %{REMOTE_ADDR}" line from my file and writes it to a new file

Code:

grep -i "RewriteCond %{REMOTE_ADDR}" /home2/test.txt > /home2/list.txt

this removes the "RewriteCond %{REMOTE_ADDR} (" part

Code:

sed -i 's/RewriteCond %{REMOTE_ADDR} (//g' /home2/list.txt

now i'm trying to use sed and the same command above to remove all the \ but i get this error:

Quote:

# sed -i 's/\//g' /home2/list.txt
sed: -e expression #1, char 6: unterminated `s' command

and i'm also trying to remove )$ at the end of the file but it's not removing it or giving me an error here's the command:

Code:

sed -i 's/)$//g' /home2/list.txt

This is where you should have been, 4 days ago.

Quote:

sed -i 's/\//g' /home2/list.txt

To get 'special characters' (like the \, /, |, etc.), to go through, try escaping them with a backslash, like:

Code:

sed 's/\\//g' /home2/list.txt

You don't need the "-i" for this..that means case-insensitive, and since you're only doing a special character, you don't need it. Putting a leading backslash will make sed treat the next character as JUST a character, rather than a 'control' character, which does something special.

This should also work for this:

Code:

sed 's/\)\$//g' /home2/list.txt

You can also (if you want to), string your sed's together on one line, like this:

Code:

cat <filename> | sed <whatever> | sed <whatever> | sed <whatever> > output.file

if i don't put a -i in this command it just outputs on the screen and not to a file

Code:

sed 's/\\//g' /home2/list.txt

also i can't get the second command to work:

Quote:

# sed 's/\)\$//g' /home2/list.txt
sed: -e expression #1, char 9: Unmatched ) or \)

steve51184 · 01-27-2009, 01:52 PM

right i've almost done it with this so far:

Code:

grep -i "RewriteCond %{REMOTE_ADDR}" /home2/test.txt > /home2/list.txt
sed -i 's/RewriteCond %{REMOTE_ADDR} (//g' /home2/list.txt
sed -i 's/\\//g' /home2/list.txt
tr -d \\n < list.txt | tr \| \\n | sort > list2.txt && mv list2.txt list.txt

the only thing i need to do is strip the )$ bit

steve51184 · 01-27-2009, 02:04 PM

nm i've done it with the following:

Code:

grep -i "RewriteCond %{REMOTE_ADDR}" /home2/test.txt > /home2/list.txt
sed -i 's/RewriteCond %{REMOTE_ADDR} (//g' /home2/list.txt
sed -i 's/\\//g' /home2/list.txt
sed -i 's/)//g' /home2/list.txt
sed -i 's/\$//g' /home2/list.txt
tr -d \\n < list.txt | tr \| \\n | sort > list2.txt && mv list2.txt list.txt

thank you very much for helping/forcing me to do this i really had fun doing it and will think/look harder next time

Hmm...not at a machine where I can test this, but it's probably got to do something with the backslashes. Sed can be picky...try:

Code:

sed 's/\\)\$//g' /home2/list.txt

and see if that gets it.

seems like i forgot i was wanting this to be a html page so i edited it to display properly:

Code:

grep -i "RewriteCond %{REMOTE_ADDR}" /home2/.htaccess > /home2/test.html
sed -i 's/RewriteCond %{REMOTE_ADDR} (//g' /home2/test.html
sed -i 's/\\//g' /home2/test.html
sed -i 's/)//g' /home2/test.html
sed -i 's/\$//g' /home2/test.html
sed -i 's/|/<br>/g' /home2/test.html

but i want to include other formatting within the file so is there a way with grep/sed/awk to include a line of code at the start/end of a file?

i've searched google but i'm not getting anything other then weird links

You can do it with a bit of simple 'cheating'. For example, the '>' character. One of them will write to a file (overwriting what ever is there), but if you put two, you will append text to it. So you could do:

Code:

echo "Beginning line of my report..." > output.file
<your shell script here> >> output.file 
echo "Ending line of my report..." >> output.file

First line puts text in the new output file. Second line is the shell script you just wrote, which will put it's output after the first line you just wrote. Third line puts the 'ending' on.

There's lots of different ways to do it, that's VERY quick, and VERY dirty.
