If the grep should match the nimsh string in $(NF-1) then consider replacing the whole-line grep by the more precise
Code:
ps -fu root | awk '$(NF-1) ~ /nimsh/ { print $(NF-1) }'

Unlike the catch-all ps -fe the ps -fu root filters for user root.
Even smarter is
Code:
ps -fu root -o args= | grep '[n]imsh'

Note the [n] trick that makes grep not find its own args in the process table.

zegrep

ZGREP(1)						    BSD General Commands Manual 						  ZGREP(1)

NAME

     zgrep, zegrep, zfgrep -- print lines matching a pattern in gzip-compressed files

SYNOPSIS

     zgrep [grep-flags] [--] pattern [files ...]

     zegrep [grep-flags] [--] pattern [file ...]

     zfgrep [grep-flags] [--] pattern [file ...]

DESCRIPTION

     zgrep runs grep(1) on files or stdin, if no files argument is given, after decompressing them with zcat(1).

     The grep-flags and pattern arguments are passed on to grep(1).  If an -e flag is found in the grep-flags, zgrep will not look for a pattern
     argument.

     zegrep calls egrep(1), while zfgrep calls fgrep(1).

EXIT STATUS

     In case of missing arguments or missing pattern, 1 will be returned, otherwise 0.

SEE ALSO

     egrep(1), fgrep(1), grep(1), gzip(1), zcat(1)
