I want to print value of SocketAcceptPort tag by using sed, in my case it's 4444. I used this regexp but no luck: sed 's/SocketAcceptPort=[0-9]+//g' file.cfg Thanks in advance.

Through sed,

$ sed -n '/^SocketAcceptPort/s/.*=//p' file
4444

It searches for the line which starts with SocketAcceptPort, if it found any then it remove all the characters upto the = symbol. Finally the remaining characters got printed. In our case it's 4444

Another sed,

sed -n 's/^SocketAcceptPort=\([0-9]\+\).*/\1/p' yourfile

If you have -E option in sed,

sed -En 's/^SocketAcceptPort=([0-9]+).*/\1/p' yourfile

You can do it with awk if you like to try:

awk -F= '/SocketAcceptPort/ {print $2}' file 
4444
