SED Help 1

[alan147]

Good morning

I have a file that is used as the input to expect, it contains commands to sftp files from a remote server and a list of files to get. I would like to check the input file against a list of previously downloaded files so that any that we have already downloaded are removed from the input list. The input file looks like this:

cd /path to files
get filename1
get filename2
cd /path to files/sub directory1
lcd /local path to files/sub directory 1
get filename 3
get filename 4
cd /path to files/sub directory2
lcd /local path to files/sub directory 2
get filename 5

the list of downloaded files looks like this

filename 2
filename 4

What I want to do is delete filename 2 and filename 4
from the input file.

I have tried a for loop reading the downloaded list then passing it through sed

for file_name in `cat downloaded_list`
do
cat input_file | sed "/$file_name/ d" > new_input_file
done

I have also tried grep -EV

neither of which have worked.

Any ideas?

Thanks

Alan

Hi

I will consider 'filename2' vs 'filename 2' a typo.

I have also tried grep -EV

Better approach then [tt]sed[/tt]. Try this :

grep -v -f alreadydownloaded.txt ftpcommand.txt > remainingftpcommand.txt

[gray]# or if your grep supports -F ( --fixed-strings )[/gray]

grep -v -F -f alreadydownloaded.txt ftpcommand.txt > remainingftpcommand.txt

Tested with GNU [tt]grep[/tt].

Brilliant. Thanks very much, I'd been trying for a couple of days to sort it out.
