"env grep" - add support for regular expression matches
When CONFIG_REGEX is enabled, the new option "-e" becomes available which causes regular expression matches to be used. This allows for example things like these: - print all MAC addresses: => env grep -e eth.*addr eth1addr=00:10:ec:80:c5:15 ethaddr=00:10:ec:00:c5:15 - print all variables that have at least 2 colons in their value: => env grep -v -e :.*: addip=setenv bootargs ${bootargs} ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}:${netdev}:off panic=1 eth1addr=00:10:ec:80:c5:15 ethaddr=00:10:ec:00:c5:15 ver=U-Boot 2013.04-rc1-00289-g497746b-dirty (Mar 22 2013 - 12:50:25) etc. Signed-off-by: Wolfgang Denk <wd@denx.de>
