Search through a word till end of line with sed in Linux Bash Shell.

Today we will see how to search starting from a word, and then select text till end of the line with sed command in linux bash shell.

Lets see step by step to understand this.

1. Search for a word say “XYZ”.

[root@ngelinux001 oracle]# cat oraclecfg.bak | grep -i XYZ
# The hostname or IP of master control gateway (XYZ)
#XYZ=your gateway domain name or IP address

2. Now select whole line using “*”.

[root@ngelinux001 oracle]# sed -i 's/#XYZ=*/XYZ="web.ngelinux.com"/g' oraclecfg.bak

3. Check out the whole text is replaced now.

[root@ngelinux001 oracle]# cat oraclecfg.bak | grep -i XYZ
# The hostname or IP of master control gateway (XYZ)
XYZ="web.ngelinux.com"
[root@ngelinux001 oracle]#

So here, we have used this trick to replace a line with our new line automatically via a command.
