Hello RudiC,
Well, I managed to trim down the dataset with "sort -u input > output", but this will only remove pure duplicates. But still, running my script on this filtered dataset will take ages :/
I presume 'sed' could help me but I can't figure out what regex I should feed him..

All,
I have a text file with several entries like below:
personname
personname.domain.com
I know there is a way to use vi to remove only the personname.domain.com line. Can someone help? I believe that it involves /s/g/ something...I just can't remember the exact syntax.
Thanks (2 Replies)

NAME
file2sdr - SDR data ingestion test program
SYNOPSIS
file2sdr configFlags fileName
DESCRIPTION
file2sdr stress-tests SDR data ingestion by repeatedly writing all text lines of the file named fileName to one of a series of non-volatile
linked lists created in a test SDR data store named "testsdrconfigFlags". By incorporating the data store configuration into the name
(e.g., "testsdr14") we make it relatively easy to perform comparative testing on SDR data stores that are identical aside from their
configuration settings.
The operation of file2sdr is cyclical: a new linked list is created each time the program finishes copying the file's text lines and starts
over again. If you use ^C to terminate file2sdr and then restart it, the program resumes operation at the point where it left off.
After writing each line to the current linked list, file2sdr gives a semaphore to indicate that the list is now non-empty. This is mainly
for the benefit of the complementary test program sdr2file(1).
At the end of each cycle file2sdr appends a final EOF line to the current linked list, containing the text "*** End of the file ***", and
prints a brief performance report:
Processing I<lineCount> lines per second.
EXIT STATUS
0 file2sdr has terminated.
FILES
No configuration files are needed.
ENVIRONMENT
No environment variables apply.
DIAGNOSTICS
Diagnostic messages produced by file2sdr are written to the ION log file ion.log.
