Grep and Awk in Windows Invalid Char in Expression Error

I am new to grep and awk - using Windows 7 (I downloaded grep and awk for windows from GnuWin).

I am have having trouble running this script:

grep -Fwf dictionary.txt frequency.txt | awk '{print $2 "," $1}'

I get the error:

awk: '{print
awk: ^ invalid char ''' in expression

I believe it might have something to do with having to use double quotes in Windows, but I tried all the combinations I can think of and still it doesn't work.

Can anyone help? Thanks

Solution

  • Escaping command line items is always a pain on Windows. As a last resort you could probably use gawk -f!

    So: your file script.awk contains:

    print $2,$1

    And you do grep -Fwf dictionary.txt frequency.txt | awk -f script.awk
