Execute bash command fails – what's my mistake?

Hi all,

I am trying to execute a bash / terminal command via Knime nodes via one of the following nodes but getting an error which likely is caused by a mistake of mine. Hope anyone has an idea …

The command is:

awk '(NR == 1)
\(FNR > 1\)' table*.csv > bigfile.csv

The following two nodes fail with:

ERROR CmdwInput            0:45       Execute failed: STDERR message:
awk: syntax error at source line 1
context is
>>> ' <<<
missing )
awk: bailing out at source line 1

External Toll fails with

ERROR External Tool (Labs) 0:58       Execute failed: Failed with exit code 2

Thanks in advance

Mike
