I am trying to make a simple backup script and i have problem creating a folder with the curent date for name
My script is that and basically the problem is on the last line
drivers=$(ls /media/)
declare -i c=0
for word in $drivers
do
echo "($c)$word"
c=c+1
done
read -n 1 drive
echo
c=0
for word in $drivers
do
if [ $c -eq $drive ]
then
backuppath="/media/$word/backup"
fi
c=c+1
done
echo "doing back up to $backuppath"
cp -r /home/stefanos/Programming $backuppath/$(date +%Y-%m-%d-%T)
Ouput:
(0)0362-BA96
(1)Data
(2)Windows
0
doing back up to /media/0362-BA96/backup
cp: cannot create directory `/media/0362-BA96/backup/2012-12-05-21:58:37': Invalid argument
The path is triply checked that is existing until /media/0362-BA96/
SOLVED : Did what janisz said the final script looks like
drivers=$(ls /media/)
declare -i c=0
for word in $drivers
do
echo "($c)$word"
c=c+1
done
read -n 1 drive
echo
c=0
for word in $drivers
do
if [ $c -eq $drive ]
then
backuppath="/media/$word/backup"
fi
c=c+1
done
echo "doing back up to $backuppath"
backup(){
time_stamp=$(date +%Y_%m_%d_%H_%M_%S)
mkdir -p "${backuppath}/${time_stamp}$1"
cp -r "${1}" "${backuppath}/${time_stamp}$1"
echo "backup complete in $1"
}
#####################The paths to backup####################
backup "/home/stefanos/Programming"
backup "/home/stefanos/Android/Projects"
backup "/home/stefanos/Dropbox"
Trying changing it to:
time_stamp=$(date +%Y-%m-%d-%T)
mkdir -p "${backuppath}/${time_stamp}"
cp -r /home/stefanos/Programming "${backuppath}/${time_stamp}"
:
is not valid on FAT (it is used to specify disk). Some of M$ invalid character works on GNU/Linux systems but it is safer to avoid them (just replace with .
). Use following date format
date +%Y_%m_%d_%H_%M_%S
It should works on most file systems but it could be too long for MS DOS FAT. More info you will find here .
