How can I find the word "UP" and replace it with "DOWN" in below data using sed, awk or grep?
document.getElementById("p1").innerHTML = "API Dev :: UP";
document.getElementById("p2").innerHTML = "API QA :: UP";
document.getElementById("p3").innerHTML = "API Reg :: UP";
document.getElementById("p4").innerHTML = "API Prod :: UP";
I am looking to find/replace one line at a time. Something like using for loop and then find/replace one line after other.
Thanks!
This is sed 101:
sed 's/:: UP/:: DOWN/'
URL=grep "document.getElementById" index.html | awk -F' ' '{print $7}'` for var in $URL do SERVICE_STATUS=curl -s --head $URL | head -n 1 | awk '{print $2}' if [[ $SERVICE_STATUS -eq "200" ]] then sed 's/:: UP/:: DOWN/' index.html fi done`echo line | sed 's/UP/DOWN/'
Where line is the string you want to replace
While @john-zwinck's answer gives you the solution for this, if you want to have a more restricted pattern, do something like below
sed -E 's/(API[[:blank:]]*[[:alnum:]]+[[:blank:]]*::[[:blank:]]*)UP/\1DOWN/'
filename
which will give you
document.getElementById("p1").innerHTML = "API Dev :: DOWN";
document.getElementById("p2").innerHTML = "API QA :: DOWN";
document.getElementById("p3").innerHTML = "API Reg :: DOWN";
document.getElementById("p4").innerHTML = "API Prod :: DOWN";
one line at a time
