tput rmam will disable line wrapping so that long lines are truncated to width of the terminal ($COLUMNS). tput smam will re-enable wrapping. I've always used tput in bash scripts but I guess it works on the command line too. Doesn't work in all terminals. See http://www.gnu.org/software/termutils/manual/termutils-2.0/html_chapter/tput_1.html

Using "wmic get * /value" within any Cygwin shell will return lots of Win/Dos newline junk ie "^M$" at the end of found value line, two lines ("$" Unix newline) above, and three below. This makes storing and or evaluating wmic queries as variables a pain. The method i suggest strips the mentioned junk, only returns the value after "OSArchitecture=", and includes only one Unix style newline. Other methods using sed|awk|cut can only handle the output of wmic cleanly when piped or using multiple sed statements. wmic OS get OSArchitecture /value | sed 's/\r//g;s/^M$//;/^$/d;s/.*=//' making wmic OS get OSArchitecture /value | grep -Eo '[^=]*$' a much cleaner and slightly less costly alternative.

This command dumps the PostgreSQL servers version out to one line. You may need to add more command line options to the psql command for your connection environment. Show Sample Output
