i created one bash script named "quicktest.sh". the task of this script is to set inotifywait on Data folder from all users home directory.
the code of quicktest.sh is down below:
function inotify_data()
{
user="$1"
if [ -d /home/$user/Data ];
then
while read -r path action file; do
echo "The file '$file' created"
chmod 0777 -R /home/$user/Data
done < <(exec inotifywait -m -r /home/$user/Data -e moved_to -e create -e modify)
fi
}
cd /home/
ls >/tmp/.grp
i=1
n=`wc -l </tmp/.grp`
while [ "$i" -le "$n" ]
do
user=`awk "NR==$i" /tmp/.grp`
echo "setting watch on $user Data Folder."
inotify_data "$user" &
i=$((i+1))
done
i have 2 users in my machine,
after running this script, i run "ps -ef | grep -i quicktest.sh" , then it will shows two process of this file.

I have put together a little script to copy pictures from the sd card run through udev and systemd service.
When it's complete I wanted it to open the file manager to the photo directory but since the script is running as root this makes problems.
How to get around this?
I am already using this script I found to display a notification, should I just make the same for the file manager? It seem a bit hacky and dirty.
#!/bin/sh
user=`whoami`
pids=`pgrep -u $user polybar`
title=$1
text=$2
timeout=$3
icon=$4
if [ -z "$title" ]; then
echo You need to give me a title >&2
exit 1
fi
if [ -z "$text" ]; then
text=$title
fi
if [ -z "$timeout" ]; then
timeout=60000
fi
for pid in $pids; do
# find DBUS session bus for this session
DBUS_SESSION_BUS_ADDRESS=`grep -z DBUS_SESSION_BUS_ADDRESS \
/proc/$pid/environ | sed -e 's/DBUS_SESSION_BUS_ADDRESS=//'`
# use it
#icon hack:
if [ -z $icon ]; then
DBUS_SESSION_BUS_ADDRESS=$DBUS_SESSION_BUS_ADDRESS \
notify-send -u low -t $timeout "$title" "$text"
else
DBUS_SESSION_BUS_ADDRESS=$DBUS_SESSION_BUS_ADDRESS \
notify-send -u low -t $timeout -i "$icon" "$title" "$text"
fi

The above code is intended to search the current working directory for any files of name f##.txt where # is a number and arrange them into directories such that fAB.txt becomes dA/fB.txt. As far as I can tell it should work however I get the below error running the code.
Moving!
mv: cannot move './f48.txt' to './d4/f8.txt': No such file or directory
Try with this.
removed unnecessary ";"
#! /bin/bash
for i in {0..9}
do
mkdir -p "d$i"
for j in {0..9}
do
if [ -e "./f$i$j.txt" ]
then

mv "./f$i$j.txt" "./d$i/f$j.txt"

Linux/sh: How to list all files one by one in specific folder,
compress each (by p7zip without save file on disk) and
upload to ftp server (by curl/ncftp) with same folder structure?
This script below work perfect but
I don't want to save 7z file on a disk each time. Because I always need to delete them all after uploaded.
I prefer stio from 7zip to curl, how to do that?

I try this but it doesn't work for me...

Here is my code:
#!/bin/bash
ps cax | grep testing > /dev/null
while [ 1 ]
do
if [ $? -eq 0 ]; then
echo "Process is running."
sleep 10
else
nohup ./testing.sh &
sleep 10
fi
done
I run it as nohup ./script.sh &
and it said nohup: failed to run command './script.sh': No such file or directory
What is wrong?
The file script.sh simply does not exist in the directory that you are issuing the command from.
If it did exist and was not executable you would get:
`nohup: failed to run command ‘./script.sh’: Permission denied
For each newly created scripts on Linux, you should first change the permission as you can see the permission details by using
ls -lah
The following content may help you:
#!/bin/bash
while [ 1 ];
do
date=`date`
pid=`ps -ef | grep "your process" | grep -v grep | awk -F' ' '{print $2}'`
if [[ -n $pid ]]; then
echo "$date - processID $pid is running."
else
echo "$date - the process is not running"
# script to restart your process
say: start the process
fi
sleep 5m
done
Make sure your script is saved as script.sh
and your executing nohup ./script.sh & from the same directory in which script.sh.
Also you can give executable permission for script.sh by
chmod 776 script.sh
or
nohup ./script.sh &
Run as
nohup sh ./script.sh &
This is my first ever bash script and I am trying to iron out all of the creases and make the script run nicely. The script is to archive all of the specified .jpg files that it finds in multiple directories on a HDD/Flash drive. There are files with the same name but different content so I have used an Md5 sum to hash them.
I am getting the directory does not exist error in Geany but it runs fine from command bar missing out two of the images. I have tried everything I can think of to fix it. Is it messy code that is doing this?
#!/bin/sh
if [ ! -d "$1" ]; then
echo Directory "$1" cannot be found. Please try again.
exit
fi
if [ $# -eq 1 ]; then
echo "usage: Phar image_path archive_path"
exit
fi
if [ -d "$2" ]; then
echo "archive exists"
else
echo "the directory 'archive' does't exist. Creating directory 'archive'."
mkdir -p ~/archive
fi
find $1 -iname "IMG_[0-9][0-9][0-9][0-9].JPG" | cat > list.txt
[ -f ~/my-documents/md5.txt ] && rm md5.txt || break
while read line;
do md5sum $line | xargs >> md5.txt
done < list.txt
sort -k 1,1 -u md5.txt | cat > uniquemd5.txt
cut -d " " -f 2- uniquemd5.txt > uniquelist.txt
sort uniquelist.txt -r -o uniquelist.txt
for line in $(cat uniquelist.txt)
do
file=$(basename $line) path="$2/file"
if [ ! -f $path ];
then
cp $line $2
else
cp $line $path.JPG
fi
done
You haven't guarded against spaces in the folder and file names everywhere.
For instance:
cp $line $2
should be:
cp "$line" "$2"
You should start by eliminating these spaces as a source to your error by evaluating each variable you are referencing and adding ""'s.
If you still get the error please provide us with the arguments used and which directory that does not exist.
