writing a special character in sed bash


writing a special character in sed bash



I have a problem, because I want to replace


QueryConnection::DefaultChannel=



with


QueryConnection::DefaultChannel=/${CHANNEL NUMBER}



e.g:
QueryConnection::DefaultChannel=/5



My code:


sed -i "s/QueryConnection::DefaultChannel=.*/QueryConnection::DefaultChannel=${NUMER_KANALU}/" "${DIR_BOTS}/bot_${COUNT_BOTS}/configTS3AudioBot.cfg"



How to make before ${NUMER_KANALU} be "/"?

Two choices:



Escape the slash:


sed -i "s/QueryConnection::DefaultChannel=.*/QueryConnection::DefaultChannel=/${NUMER_KANALU}/" "${DIR_BOTS}/bot_${COUNT_BOTS}/configTS3AudioBot.cfg"



Use a different delimiter around the s parameters:


s


sed -i "s#QueryConnection::DefaultChannel=.*#QueryConnection::DefaultChannel=/${NUMER_KANALU}#" "${DIR_BOTS}/bot_${COUNT_BOTS}/configTS3AudioBot.cfg"
