How do I determine the uptime on a SunOS UNIX box in seconds only? On Linux, I could simply cat /proc/uptime & take the first argument: cat /proc/uptime | awk '{print $1}' I'm trying to do the same on a SunOS UNIX box, but there is no /proc/uptime. There is an uptime command which presents the following output: $ uptime 12:13pm up ...

Hi, I'm using the openssl utility of debian in order to create a certificate. The certificate paramemters are given in a configuration file, which is made of key-value pairs.

Does find utility accepts condition in form of the 'wc -c'? Or maybe some other utilities should be pi...
Some commands like svn log, for example will only take one input from the command line, so I can't say grep 'pattern' | svn log.
