script to read number from config file

Hi All,

I've been making some scripts recently and have gotten to the stage where I want to do the following:
We have a ftp file setup (call it folder A) and I want to make it so that on a nightly basis the files are moved from folder A to an archive (folder B) then once a week I will Tar the contents of this folder.

I have created the following script:

Code:

#get the counters id for a new file

read counter.ini c1



#make a new folder for the archive

cd <Folder B>

mkdir $c1



move all folders into the folder

cd <Folder A>

mv *.* <Folder B>/$c1



#set permissions

setfacl -Rm g:...<this bit works>





#increment the counter by 1

cd /data/scripts/archivescan/

let c2=$c1+1



mv counter.ini counter.old

echo $c2 > counter.ini



setfacl -Rm g:...<this bit works>

The file "counter.ini" contains only a number and nothing else
This is the current method that I have chosen to make the folders unique, Unless there is an option to get the current date and use that in a folder name?

Thanks in advance

Yes. Using the date command in command substitution you can create a folder name with date in any format you want, e.g.

Code:

mkdir $(date +%Y-%m-%d_%H%M)

if you use the format yyyymmdd the directories will be sorted alphabetically with the ls command, so that the most recent one is at the bottom of the list.

Excellent, Thanks for the help there.

Is there a way that I can check if the file is empty before continuing?
So, in my script i'll create the target folder B but if Folder A is empty it stops?

There are different ways to check if a folder is empty. Here is an example:

Code:

[[ -z $(ls FolderA) ]] && exit

Here's another way purely using bash inbuilts

Code:

shopt -s nullglob

[[ -z "$(printf "%s" *)" ]] && echo "empty"

That was just the ticket.
Now working perfectly.

If anyone would like a copy of my scripts they are below:

This moves files from Folder A to Folder B/Today's Date (D-M-Y format)

Code:

#!/bin/bash



#make a new folder for the archive

cd <Folder B>

mkdir $(date +%d-%m-%Y)



#check if folder A is empty before continuing



cd <Folder A>

shopt -s nullglob

[[ -z "$(printf "%s" *)" ]] && echo "Scans folder is empty

Checked on $(date +%d-%m-%Y) at $(date +%H-%M)

------" >> /scripts/archivescan/archive.log && exit



#Folder A has Data

        #goto the scans folder

    cd /data/headoffice/departments/scan/

    #log the files to be moved

    echo "Files to be moved to scan_archive:" >> /scripts/archivescan/archive.log

    ls -R >> /scripts/archivescan/archive.log

    echo "------" >> /scripts/archivescan/archive.log

    

    #now move the files

    mv * <Folder B>/$(date +%d-%m-%Y)

    

    #set permissions

    #if required

    

    #log notice to show successful run

    cd /data/scripts/archivescan

    echo "Scan Files successfully moved on $(date +%d-%m-%Y) at $(date +%H-%M)" >> archive.log

    echo "------" >> archive.log

This then creates a GZip Tar of the folders in the archive location:

Code:

#change to the scan_archive folder

cd <Folder B>



#make a list of the folders to be archived into the log file

echo "Files to be archived:" >> /scripts/archivescan/archive.log

ls | grep -v *.tgz >> /scripts/archivescan/archive.log

echo "------" >> /scripts/archivescan/archive.log



#Compress the files into a tar (gzip compressed) file and remove source files

tar cfz archive_$(date +%d-%m-%Y_%H-%M).tgz * --exclude=*.tgz --remove-files



#log notice to show successful run

cd /scripts/archivescan

echo "Scan Files successfully archived on $(date +%d-%m-%Y) at $(date +%H-%M)" >> archive.log

echo "------" >> archive.log

You can use new_dir="$(mktemp -d /the/path/prefixXXXXXX)" to create a unique directory. Note that the 6 Xs are literal. mktemp will create the directory and echo its name.
