small bash script copy one file to list of directories on file
 

Hi i want write script to copy robots.txt file to all of the web_root directory this should be only file if not available on root directories.

there is more than 50 web_root directories.
and need to send a mail if not available ?

#!/bin/bash
file=/home/shanaka/robots.txt
for dir in /home/deploy/*/public_html
do
cp "$file" "$dir"
done

i have write above that, it is only can copy files to all directory, but not check whether available or not, sending mail, can you help me to do this ?

maybe something like this:

thanks friend it was really help,but i want to send mail if robots.txt file not available on location, which should be with include directory location which is not available. but now all the files are copping before check the file availability, therefore mail is not working.

i have edited your script. but it is not working giving error. can you help me on this ?


#!/bin/bash
file=/home/shanaka/robots.txt

for dir in /home/shanaka/test/*/public_html
if [ ! -e $dir/robots.txt ]
then
mail -s "404: file not found " lahirushana@gmail.com
do cp "$file" "$dir"
fi
done

You need the "do" after the for statement, not before the cp command.

then it is not sending mail, bcz it is coping file before check the file availability

HI friends wrote something like below, thanks for helping me alot,


but i need help again, if the one file is difference, it is show all the files as different, how i show only that file is different or only show the different files

I do not really understand what do you need, but here are some tips:

thanks yo

thanks you very much friends,
what i realy want is check robots.txt file in all web root, if it is there then, theck whether it is disallow or not. if it is not, i need to copy robots.txt file to not available web directories.

this is my result for previous code.

/home/shanaka/test1/project1/public_html is not same
/home/shanaka/test1/project2/public_html is not same
/home/shanaka/test1/project3/public_html is not same
/home/shanaka/test1/project4/public_html is not same
/home/shanaka/test1/project5/public_html is not same

so here only "/home/shanaka/test1/project1/public_html is not same directory file only differet, but it is showing all the directory as wrong,

there for i want to grep different one only. and copy file to those directories.

Hi,

Im getting below error please help me

./robo.sh: line 12: [: : integer expression expected
./robo.sh: line 12: [: : integer expression expected
./robo.sh: line 12: [: : integer expression expected
./robo.sh: line 12: [: : integer expression expected

$result is probably not a number (what are you expecting it to be ?).

please change the first line of your script to #!/bin/bash -x and show us the result.

Hi friend thanks for the help, issue is resolve, but i dont have an idea how is working, i have publish my code in below, now only error directory will be show as show in echo as i want, can you explain how it is work and is this the right way to do this if you dont mind.

#!/bin/bash
file=/home/shanaka/robots.txt
for dir in /home/shanaka/test1/*/public_html
do
if [ ! -e $dir/robots.txt ]
then
ls -l /home/shanaka/test1/*/public_html/ | mail -s "404: file not found" lahirushanaka@gmail.com
cp "$file" "$dir"

else
result=$(diff $file $dir/robots.txt > /dev/null;)
if [ "$?" -ne 0 ]
then
echo $dir is not same
cp "$file" "$dir"
fi
fi
done
