Good Evening All,
I’m currently having a bash syntax issue when I try to run the following command in my terminal, the
bash: syntax error near unexpected token `(‘
error message pops up after I run the below code:
/mnt/grads/bin/wgrib2 /home/aaron/grads/data/sref_prob/20140530/15Z/sref.20140530.t15z.prob.grib2 -match ^(255|371|487|623|759|895|1031|1187|1343|1499|1655|1811|1967|2123|2279|2435|2591|2747|2903|3059|3215|3371|3527|3683|3839|3995|4151|4307): -grib /home/aaron/grads/data/sref_prob/20140530/15Z/test.grib2
I realize that not many people on here probably have experience using wgrib2 but, this seems like a syntax error, not an issue with the program…

Answer
Parentheses and pipes have special meaning to the shell, you need to quote or escape them:
/mnt/grads/bin/wgrib2 /home/aaron/grads/data/sref_prob/20140530/15Z/sref.20140530.t15z.prob.grib2
-match '^(255|371|487|623|759|895|1031|1187|1343|1499|1655|1811|1967|2123|2279|2435|2591|2747|2903|3059|3215|3371|3527|3683|3839|3995|4151|4307):'
-grib /home/aaron/grads/data/sref_prob/20140530/15Z/test.grib2
