Export variables to another script - linux

Question

I am making 2 scripts. The first script is going to take a file, and then move it to a directory named "Trash". The second script will recover this file and send it back to it's original directory. So far I have the first script moving the file correctly.
Here is my code so far:
For delete.sh
FILE=$1
DATEDELETED=$(date)
DIRECTORY=$(pwd)
mv $1 Trash
echo $FILE
echo $DATEDELETED
echo $DIRECTORY
Output:
trashfile
Sun Mar 2 21:37:21 CST 2014
/home/user
For undelete.sh:
PATH=/home/user/Trash
for file in $PATH
do
$file | echo "deleted on" | date -r $file
done
echo "Enter the filename to undelete from the above list:"
EDIT: So I realized that I don't need variables, I can just list all the files in the Trash directory and edit the output to what I want. I'm having a little trouble with my for statement though, I'm getting these two errors: ./undelete.sh: line 6: date: command not found
./undelete.sh: line 6: /home/user/Trash: Is a directory. So I'm not exactly sure what I'm doing wrong in my for statement.
Here is the expected output:
file1 deleted on Tue Mar 16 17:15:34 CDT 2010
file2 deleted on Tue Mar 16 17:15:47 CDT 2010
Enter the filename to undelete from the above list:

Answer 1

Well I've accomplished what could be a workaround for what your scenario is trying to accomplish.
Basically you can enter echo "script2variable=$script1variable" >> script2.sh from script1.sh. Then use the source command to call that script later from any script you desire. Might have to just play with the theories involved.
Good Luck!
Delete Script file
#!/bin/bash
# delete.sh file
# Usage: ./delete.sh [filename]
#DATEDELETED=$(date) #not best solution for this kind of application
DIR=$(pwd)
fn=$1
#Specify your trash directory or partition
trash=~/trash
#Set path and filename for simple use in the script
trashed=$trash/$fn.tgz
#Send variables to new manifest script.
echo "#!/bin/bash" > $1.mf.sh
echo "DIR=$DIR" >> $1.mf.sh
# Questionable need?
#echo "DATEDELETED=$DATEDELETED" >> $1.mf.sh
echo "mv $1 $DIR" >> $1.mf.sh
echo Compressing
tar -cvpzf $trashed $1 $1.mf.sh
if [ $? -ne 0 ]; then
echo Compression Failed
else
echo completed trash compression successfully
echo Trashbin lists the file as $trashed
rm $1 -f
rm $1.mf.sh -f
echo file removed successfully
fi
exit 0
Restore Script File
#!/bin/bash
# restore.sh
# Usage: ./restore.sh
# filename not required for this script, use index selection
fn=$1
#SET LOCATION OF TRASH DIRECTORY
trash=~/trash
listfile=($(ls $trash))
#SET COUNTER FOR LISTING FILES = 0
i=0
#THIS IS JUST A HEADER FOR YOUR OUTPUT.
clear #cleanup your shell
echo -e INDEX '\t' Filename '\t' '\t' '\t' Date Removed
#Echo a list of files from the array with the counter.
for FILES in "${listfile[#]}"
do
echo -e $i '\t' $FILES '\t' "deleted on $(date -r $trash/$FILES)"
let "i += 1"
done
#Output total number of items from the ls directory.
echo -e '\n' $i file\(s\) found in the trash!
# 1 Offset for 1 = 0, 2 = 1, and so on.
let "i -= 1"
#Require input of a single, double, or triple digit number only.
#Loop back prompt if not a number.
while true;
do
read -p "Enter an index number for file restoration: " indx
case $indx in
[0-9]|[0-9][0-9]|[0-9][0-9][0-9] ) break ;;
* ) read -p "Please enter a valid number 0-$i: " indx ;;
esac
done
#
script=$(echo ${listfile[$indx]}|sed 's/\.tgz/\.mf.sh/g')
tar -xvpzf $trash/${listfile[$indx]}
rm $trash/${listfile[$indx]}
sleep 2
chmod +x $script
source $script
rm $script

Answer 2

Run the script with source
source <yourscript>
or
. ./<yourscript>
In your case
. ./delete.sh && ./undelete.sh
Hope this will help
