| Hi
I have some files on /bak/data/a.dbf
b.dbf
x.dbf so on
I have a text file defining where these files should be copied to ie
/data/sid/01/a.dbf
/data/sid/02/b.dbf
/data/sid/01/x.dbf and so on
How do I write a shell script to check whether a.dbf exists on
/bak/data/a.dbf and if its there copy it from /bak/data/a.dbf to
/data/sid/01/a.dbf and so on...
thanks

You need to read the files from the textfile one by one
while read -r pathname
do
: ...
done <textfile
then extract the filename from the pathname
filename=${pathname##*/}
then test existance
if [ -f "/bak/data/$filename" ]
then
: ...
fi
and finally a copy (overwrite) if it's existing
targetdir=${pathname#%/*}
cp "/bak/data/$filename" "$targetdir"

The posted code is shell code.
Put the cp command block into the if block
and the resulting if block into the while block.
