Grep issue

davie_93 · 10-16-2013, 08:35 PM

Hi I'm new here and just needed a small helping hand

The problem is that I am trying to restore a file to a location that it had previously - unfortunately I know what the error is but don't know how to solve it.

for example the file test1 has a directory of /home/dave/test1 it is then moved to a dustbin type feature (directory). When retrieving the file and trying to put it back I cannot as the previous location is /home/dave/test1. Any way to sort of grep/find the test1 out - has to be generic for all files trying to do the same.

Code:

if [ "$1" == "" ]; then
echo "You must enter the file's name you are wanting to restore"

elif [ ! -e "/home/dave/dustbin/$1" ]; then
echo "No file in dustbin named '$1' please check spelling"

else

grou=$(basename "$1") 
location=`grep $1 /home/dave/fileorigin` 
filename=`basename "$location"`	

mv $filename $location

#echo $filename
#echo $location				

fi

If I understand, there's only one file in the directory and you want to move file
/home/dave/test1/test1 to file /home/dave/test1.

You can do that in a way equivalent to this:

Code:

mv /home/dave/test1 /home/dave/TT
mv /home/dave/TT/test1 /home/dave/test1
rmdir /home/dave/TT

try this: (go to /home/dave directory and move it from there)

cd /home/dave

mv -r ./dustbin /home/dave

Good luck!!!

It was kind of a eureka moment I answered my own question just use the opposite of basename when trying to remove the suffix.

Thanks for all the help guys!

Code:

elif [ ! -e "/home/dave/dustbin/$1" ]; then
echo "No file in dustbin named '$1' please check spelling"
else
fio=`grep $1 /home/dave/fileorigin`
location=`dirname "$fio"`
filename=`basename "$fio"`
