Searching for the popular compiler produces unexpected results
$ cygcheck -p 'g++.exe'
Found 0 matches for g .exe
$ cygcheck -p 'g\+\+.exe'
Found 0 matches for g\ \ .exe
How can I include a literal '+' (plus character) in my search?

The point was that in any case it was not doing what was wanted nor expected, and an extra set of brackets [[:punct:]] are needed to search for punctuation. >> ITYM: >> $ cygcheck -p mingw32-g[[:punct:]][[:punct:]] | sed '2,$s/\s.*//' Not sure what if anything glob does with double brackets - anything I tried with ls always returned the search string e.g. $ ls /etc/setup/[[a-z]]* ls: cannot access '/etc/setup/[[a-z]]*': No such file or directory It does not seem to have any support for accented character classes or the ilk e.g. re [[:a:][:e:][:i:][:o:][:u:]] which could be useful searching for UTF-8 filenames. > Or, with proper quoting to shield yourself from globbing based on the > contents of the current directory: > cygcheck -p 'mingw32-g[[:punct:]][[:punct:]]' | sed '2,$s/\s.*//' Always a concern for conscientious scripters and especially on Windows where characters which may rarely be encountered on Unix systems are often lurking to catch unwary scripters. -- Take care.
