I have a directory containing files and an md5sum.txt file. I add a file new files to the directory. I would like add md5sum sums for all files that are not in md5sum.txt.
Is there a simple way to do it?

You can try this little number:
#We want the seperator to be newlines, not spaces
IFS="$(echo -e "\n\r")"
for EACHFILE in `ls -1`
do
# If grep can't find the filename in that text file
if ! egrep -q " $EACHFILE$" md5sum.txt; then
md5sum $EACHFILE
fi
done
This assumes that the text file is like this:
964e6b94e921b5f0879b41956b787050 test.file
Which is standard output

In OSX I had to change the second line to: IFS=$'\n' – Josep Valls – 2015-09-14T16:47:58.817
1What kind of script are you looking for? What operating system are you using? – innaM – 2009-11-04T21:35:59.430
you basically have to script reading in your md5sum.txt and directory listing and weed out from there. i'd probably choose perl for the task. – quack quixote – 2009-11-04T21:49:11.777
