I have two files.
file.txt
and delete.txt
file.txt
contains the following for ex.:
/somedirectory/ /somedirectory2/somefile.txt /anotherfile.txt
delete.txt
contains:
/somedirectory/ /somedirectory2/somefile.txt
I need to delete the rows from file.txt
that are contained within delete.txt
cat file.txt
should result with:
/anotherfile.txt
So far I’ve tried this with no luck:
while read p; do line=$p; sed -i '/${line}/d' file.txt; done < delete.txt
I don’t receive any error, it just doesn’t edit my file.txt
file. I’ve tested the while loop with an echo ${line}
and it works as expected in that scenario.
Any suggestions?
Note: the while loop above doesn’t work as expected even when I took the forward slashes off of the files.

With a simple grep
:
grep -vFxf delete.txt file.txt > temp.txt && mv temp.txt file.txt
