I am wanting to monitor whether a directory's transport is connected with bash.
I currently have the shell:
#!/bin/bash
mounts=('/mount1' '/mount2' '/mount3' '/mount4' '/HDD');
for mount in "${mounts[#]}"
do
if grep -qs ${mount} /proc/mounts
then
echo "${mount} is mounted."
else
#force remount
sudo umount -l ${mount}
sudo fusermount -uz ${mount}
sudo mount ${mount}
fi
done
but grep -qs ${mount} /proc/mounts does not actually check the endpoint? what should I do instead?

I cannot figure out what's wrong with my bash script. When I run it in terminal, command by command run every command separately in terminal, it works.
#!/bin/bash
sudo su <<EOF
mkdir /home/ubuntu/backup/
cp "$(ls -t /usr/lib/unifi/data/backup/autobackup | head -1)" /home/ubuntu/backup/
curl --insecure --user root:password -T "$(ls -t /home/ubuntu/backup/ | head -1)" sftp://vps2.duckdns.org:/root/backup.unf
EOF
However, when I run the above bash script, give me plenty of erros
bash -v test.sh
#!/bin/bash
sudo su <<EOF
mkdir /home/ubuntu/backup/
cp "$(ls -t /usr/lib/unifi/data/backup/autobackup | head -1)" /home/ubuntu/backup/
curl --insecure --user root:password -T "$(ls -t /home/ubuntu/backup/ | head -1)" sftp://vps2.duckdns.org:/root/backup.unf
EOF
ls: cannot access '/usr/lib/unifi/data/backup/autobackup': Permission denied
ls: cannot access '/home/ubuntu/backup/': No such file or directory
cp: cannot stat '': No such file or directory
curl: (78) Could not open remote file for reading: SFTP server: No such file
Any help will be very much appreciated!
TIA
It's trying to execute the command substitutions in the original shell, which runs with the regular user's permissions. They need to be executed by su. Quote the EOF token to prevent expansions in the here-document.
sudo su <<'EOF'
I am trying to create a script I can provide to those who will use an academic game I am making. I am trying to do the following:
Verify that Apache2 is installed and Running
If Apache2 is installed, move a folder containing the website files to /var/www/html while backing up apache's original index.html
The code is as follows:
#!/bin/sh
acm=[]
cnn=[]
gnu=[]
ieee=[]
if [pgrep -x "apache2" > /dev/null]; then
echo "Apache 2 Installed and Running!"
if [ -d "$HOME/acmDL" ]; then
sudo mkdir /var/www/bak
sudo mv /var/www/html/index.html /var/www/bak
sudo mv acmDL /var/www/html/
cd /var/www/html/
sudo mv acmDL/* .
exit
elif [ -d "$HOME/cnnDL" ]; then
sudo mkdir /var/www/bak
sudo mv /var/www/html/index.html /var/www/bak
sudo mv cnnDL /var/www/html/
cd /var/www/html/
sudo mv cnnDL/* .
exit
elif [ -d "$HOME/gnuDL" ]; then
sudo mkdir /var/www/bak
sudo mv /var/www/html/index.html /var/www/bak
sudo mv gnuDL /var/www/html/
cd /var/www/html/
sudo mv gnuDL/* .
exit
elif [ -d "$HOME/ieeeDL" ]; then
sudo mkdir /var/www/bak
sudo mv /var/www/html/index.html /var/www/bak
sudo mv ieeeDL /var/www/html/
cd /var/www/html/
sudo mv ieeeDL/* .
exit
else
echo "Provided websites not found... Are you using a custom website?"
fi
else
echo "Please check apache2... It may not have installed correctly"
fi
The error I keep getting is syntax error near unexpected token `elif' on line 15.
As you can see, I even tried moving the boolean expression [ - d "$HOME/site" ] to their own variables, but then the error becomes : -d: command not found and the error on line 15.
Is what I am trying to do impossible, or am I missing something undocumented and yet completely obvious (like a handful of my previous posts)?
This is being run on a minimal installation of Ubuntu 18 on a Virtual Machine. The site directories are shared by Filezilla. Script written in Notepad++ on Windows 7 x64.
First of all, can you rewrite it like this?
Please tell me the execution result.
This is wrong.
if [pgrep -x "apache2" > /dev/null]; then
This is correct.
pgrep -x "apache2" > /dev/null
if [ $? -eq 0 ]; then
I have a script that try to mirror a specific directory from a local server to a remote one. It looks like that:
inotifywait -mr --format '%w%f' -e close_write -e moved_to -e delete /mydir | \
while read FILECHANGE
do
if [ -f $FILECHANGE ]
then
rsync --bwlimit=4096 --progress --relative -vrae 'ssh -p 22' $FILECHANGE $REMOTEHOST:/
else
ssh -p 22 $REMOTEHOST "rm $FILECHANGE"
fi
done
In case of multiple create of files, as for example a touch command:
touch 1 2 3
The 3 files are well transfered.
But if I delete several files at once:
rm -f 1 2 3
Only the first 1 is deleted.
If I replace the ssh command by just an echo $FILECHANGE, the 3 files are well displayed in the console. So it seems the problem come from the ssh command, but I can't explain why and solve it.
Anyone as an idea?
Well, I found the issue: it seems that the ssh command was eating the output of the inotifywait command when run. So, to prevent that, I add the 0<&- redirection after the ssh, to close the stdin.
inotifywait -mr --format '%w%f' -e close_write -e moved_to -e delete /mydir | \
while read FILECHANGE
do
if [ -f $FILECHANGE ]
then
rsync --bwlimit=4096 --progress --relative -vrae 'ssh -p 22' $FILECHANGE $REMOTEHOST:/
else
ssh -p 22 $REMOTEHOST "rm $FILECHANGE" 0<&-
fi
done
Now it works.
this shell script should add everything put in the folder to transmission. With one folder it works fine, but when i add more then one folder at the same moment it ignores the second one.
while true;
do
file=$(inotifywait -e moved_to --format %f /srv/watchfolderfilme)
file="/srv/watchfolderfilme/$file"
transmission-create -o $file.torrent -s 16384 -t http://0.0.0.0:6969/announce $file
mv $file /srv/downloads
chmod 0777 $file.torrent
cp $file.torrent /srv/newtorrentfiles
mv $file.torrent /srv/watchfoldertorrents
done
Rethough my solution and found a better one that works fine for multiple adds
inotifywait -m /srv/watchfolderfilme -e create -e moved_to |
while read path action file; do
# echo "The file '$file' appeared in directory '$path' via '$action'"
chmod 0777 $path$file
transmission-create -o /srv/newtorrentfiles/$file.torrent -s 16384 -t http://0.0.0.0:6969/announce $path$file
mv $path$file /srv/downloads
chmod 0777 /srv/newtorrentfiles/$file.torrent
cp /srv/newtorrentfiles/$file.torrent /srv/watchfoldertorrents
done
Which of the following commands accept the --preserve-root flag?
chgrp
chmod
rm
rsync
for cmd in chgrp chmod rm rsync; do
man "$cmd" | grep -q "preserve-root" && echo "$cmd"
done
OR
$ for i in chgrp chmod rm rsync; do $i --help | grep -q '\-\-preserve\-root' && echo $i; done
chgrp
chmod
rm
