Hello, i have a server that has hundreds of domains that are use for email, the actual sites are just used to point users to main site and act as search engine boosters.

Obviously i do not want to changed each file one by one, and though i am new to linux i know that i can create a shell script to copy the new index.html to all the individual /home/domain/public_html/ directories.

Can any one help me out with how best to acheive this?


many thanks

for dirname in domain1 domain2 domain3
do
cp index.html /home/${dirname}/public_html
done

Or you could do something like

for dirname in `ls /home/domain*`
do
cp index.html /home/${dirname}/public_html
done

thanks for reply, this looks good if i want to changed index.html file in all

/home/domain/public_html/

which i don't, it need it to be selective

somthing like

cp index.html /home/${domain1,domain2,domain,7,domain15}/public_html
done

Just as Mik said:

for dirname in domain1 domain2 domain15
do
cp index.html /home/${dirname}/public_html/
done

eithir i am slow to undestand or you do not understand what i want to do.

The syntax given seems to be to copy new index.html to one domain at a time or all domains at same time.


I want to automatically copy new index.html file to a list of selected domains, not all my domains.

This why i asked how to incluede list of domains 'user name' dir
In below how would i insert a list of domain user dir, where
{list} is where the list would go.

cp index.html /home/${list}/public_html
done

An another way:
it's

for domain in domainx domainxy domaintotallydifferent
do
cp index.html /home/${domain}/public_html
done

Note that its totally up to you which domain-names you choose in your "in ..." List.

you might also do something like

for domain in domain1 steave domain17 www
do ...

to have the index.html copied to the public_html dir of the "users"
domain1, steave, domain17 and www

Steave.

Hello, thanks for help but i am really confused now


Ok i have 10 domains and i wish to change the index.html in 5 of them. The dir structure is like this

/home/domain1/public_html/
/home/domain2/public_html/
/home/domain3/public_html/
/home/domain4/public_html/
/home/domain5/public_html/
/home/domain6/public_html/
/home/domain7/public_html/
etc

i create a shell script with syntax

cp index.html /home/${domain1 domain2 domain3 domain4 domain5 }/public_html
done


would this work ?

thanks for help

what kind of syntax do you mean?

what you said, "cp index.html /home/${domain1 domain2 domain3 domain4 domain5 }/public_html"

is completely wrong (no offense!), bash can't do that, and specifying a program to run like that would not work, as you'd be using 'cd' not your own script by the way you wrote that, you have been given pretty much the same solutio tweice now, whcih does exactly what you are after. what else do you require that their solutions don't provide?

personally i'd use a shift call to move the script parameters along, and call $2 continuously in a for loop, but there's loads of ways of doing the same thing.

you seem to be being somewhat dogged in this illegal syntax you seem to be after. I'd suggest reading up on shell scripting. look at some of the books on the link on my signature

OK. Probably some explanation here:

for dirname in astring anotherstring somestring
do
- code -
done

lets $dirname be (in the order stated) all of the strings in the list followin the "in"

so inside the do-done segment, you can use $dirname to -in your case copy- stuff to the desired directories.

Got it now?

Very very confusing. To confuse you even more try this:

export list="domain1 domain2 domain5"

for dirname in ${list}
do
cp index.html /home/${dirname}/public_html
done


Still the same thing but maybe it makes it clearer for you.

filename=$1
shift
for dirname in $*
do
cp ${filename}/home/${dirname}/public_html
done

removes the need to set a variable. just state all names as parameters

Ok i think you lot are winding me up

let me see if i have got it,

if i create a file called copy-index.txt with the following syntax in it and set permission to execute it will do the required task.

syntax in file copy-index.txt =



filename=$index.html
shift
for dirname in $domain1 domain 2 domain3
do
cp ${filename}/home/${dirname}/public_html
done


many thanks guys

nah, you see now that's a general jumble of al the different solutions... you really need to read up on shell scripting. the way i've done it here is a little more subtle i think than most other solutions, and is more flexible. i'll let you fine out exactly what shift and $* actaully mean.. but this DOES work...

[chris@trevor chris]$ cat script
filename=$1
shift
for dirname in $*
do
echo cp $filename /home/$dirname/public_html
done
[chris@trevor chris]$ ./script a b c d e
cp a /home/b/public_html
cp a /home/c/public_html
cp a /home/d/public_html
cp a /home/e/public_html

yeah? obviously, just remove the word 'echo' and it'll go copy the stuff, rather than just pritning out the command like i've done there.

and why do you want to call it blah.txt? it's not a text file, it's a script file. generally you wouldn't ever give script files a suffix at all.

thanks i will give it a try after i do a little more reading on subject.

what your not understanding is this


the word for sets a variable


for variable in something anything somethingelse


now all of the words values to the right of in will be assigned to $variable one at a time in the loop.

since there are three words the loop will run three times.

1st run

do

echo $variable

is the same as

echo something

done

2nd run

do

echo $variable

is the same as

echo anything

done

3rd run

do

echo $variable
is the same as

echo somethingelse

done



that being said, the shift is better
