top -c command in linux to filter processes listed based on processname
... pgrep to get pid's of matching command lines:
top -c -p $(pgrep -d',' -f string_to_match_in_cmd_line)
top -p expects a comma separated list of pids so we use -d',' in pgrep. The -f flag in pgrep makes it match the command line instead of program name.

Why does javascript replace only first instance when using replace? [duplicate]
...C#/.NET class library (and most other sensible languages), when you pass a String in as the string-to-match argument to the string.replace method, it doesn't do a string replace. It converts the string to a RegExp and does a regex substitution. As Gumbo explains, a regex substitution requires the g...
Purpose of Trigraph sequences in C++?
...h less dangerous since they get processed as tokens, so a digraph inside a string literal won't get interpreted as a digraph.
