Calling z by itself causes an error

[adambair]

On my system (OS X 10.5.7) calling z without arguments results in the errors below. Everything else seems to work as expected.

    → z
    awk: syntax error at source line 36
     context is
    print $0 >> FILENAME >>>  ".tmp" <<< 
    awk: illegal statement at source line 37
    awk: illegal statement at source line 37
    mv: rename /Users/adam/.z.tmp to /Users/adam/.z: No such file or directory

Thanks, it looks like some versions of awk don't like the FILENAME variable. I'll look at this on a mac and try to fix. I'm surprised that other stuff still works, cause this looks like it would zero out your datafile.

Hrm, I think you're right... it worked for a while until I ran it without the arguments -- then it looks like it did zero out my data file :)

pass tmpfile name to awk in a variable. BSD awk (which OSX appears to use) doesn't like to redirect to concatenated filenames, and FILENAME is not available in the BEGIN clause, which is where i'd like to concatenate it, so this seemed the best approach. Closed by eacb0e8
