bash - Deleting Inactive 5 days Old Files -

my aim delete more 5 days old files no longer used process. starter have written following script, not work, says line 10 command not found.

home=~/var  cd $home  f in `find . -type f`;   if [`lsof -n $f`];         echo $f   fi  done 

hmm ye not being done try this:

#!/bin/bash       dir=$home/var      ##########################################################      ## files older 5 days , recursive value set 1       # f in $(find  $dir -mtime +5 -maxdepth 1 -type f);      ##########################################################      f in $(find  $dir -type f);         # run lsof , pattern a-z send dev null         lsof -n $f |grep [a-z] > /dev/null         # if found exit status 0 or success         if  [ $? = 0 ];            echo "$f in use -->"         else                 echo "file $f not in use"         fi     done 

in script had defined home ~/var - using squigly line in scripting try , stay away from. secondly changing environment variable's value within script.. try command line

env|grep home 

this new method lot cleaner

now here pointer may mean need make further changes...

will script running in cron job ? running cron entry existing user ? if set root run above fail show how:

echo $home /home/myuser  sudo -i  echo $home /root 

notice how ~ or $home value home has changed.. if decide run cron entry user try

scriptuser="your_user" getent passwd $scriptuser|awk -f":" '{print $6}' 

if current user sudo su - or sudo -i executing script try :

getent passwd $(logname)|awk -f":" '{print $6}'
