I have a cron job which runs every 30 minutes to generate log files with time-stamp like this:
test20130215100531.log,
test20130215102031.log
I would like to create one folder daily with date time-stamp and push log files in to respective date folder when generated.
I need to achieve this on AIX server with bash.
Maybe you are looking for a script like this:
#!/bin/bash
shopt -s nullglob # This line is so that it does not complain when no logfiles are found
for filename in test*.log; do # Files considered are the ones starting with test and ending in .log
foldername=$(echo "$filename" | awk '{print (substr($0, 5, 8));}'); # The foldername is characters 5 to 13 from the filename (if they exist)
mkdir -p "$foldername" # -p so that we don't get "folder exists" warning
mv "$filename" "$foldername"
echo "$filename $foldername" ;
done
I only tested with your sample, so do a proper testing before using in a directory that contains important stuff.
Edit in response to comments:
Change your original script to this:
foldername=$(date +%Y%m%d)
mkdir -p /home/app/logs/"$foldername"
sh sample.sh > /home/app/logs/"$foldername"/test$(date +%Y%m%d%H%M%S).log
Or if the directory is created somewhere else, just do this:
sh sample.sh > /home/app/logs/$(date +%Y%m%d)/test$(date +%Y%m%d%H%M%S).log
You should use logrotate! It can do this for you already, and you can just write to the same log file.
Check their man pages for info: http://linuxcommand.org/man_pages/logrotate8.html
