Thanks. I don't know were '$' is missing. can you please point that out? I also found out that '<<<' represent 'here'.
Code:
read N L <<< $(grdinfo data.grd | awk '{print $10,$5}')

what is the implication of "<<<" and how can I test the output from this command line? I tried:
Code:
read N L <<< $(grdinfo data.grd | awk '{print $10,$5}')
echo N L

NAME
sha384sum - compute and check SHA384 message digest SYNOPSIS
sha384sum [OPTION]... [FILE]... DESCRIPTION
Print or check SHA384 (384-bit) checksums. With no FILE, or when FILE is -, read standard input. -b, --binary read in binary mode -c, --check read SHA384 sums from the FILEs and check them --tag create a BSD-style checksum -t, --text read in text mode (default) The following five options are useful only when verifying checksums: --ignore-missing don't fail or report status for missing files --quiet don't print OK for each successfully verified file --status don't output anything, status code shows success --strict exit non-zero for improperly formatted checksum lines -w, --warn warn about improperly formatted checksum lines --help display this help and exit --version output version information and exit The sums are computed as described in FIPS-180-2. When checking, the input should be a former output of this program. The default mode is to print a line with checksum, a space, a character indicating input mode ('*' for binary, ' ' for text or where binary is insignificant), and name for each FILE. AUTHOR
