Subject: | how to use gnu parallel and grep with a space |
Date: | Sun, 11 May 2014 09:31:13 +0000 |
Hello,
I am trying to use gnu parallel and grep as follows cat tmp | parallel -j1 grep "^{} " ~/datafile.txt (notice one space between {} and ") One line in tmp contains 101 and unfortunately with the above statement I get 101 299.2599 -3.6514901 1013 185.00003 -6.7468192 1014 188.6323 9.7729794 which I don't want grep "^101 " datafile.txt works fine though I changed grep "^{} " with grep "^{}\" but that too gives same results as before. Is there an easy solution for this? Thanks shantanu |
