CodePudding user response：

Using sed

$ sed 's/$/:8080/' input_file
235.67.89.65:8080
23.66.34.90:8080
12.34.98.45:8080
12.45.77.100:8080

CodePudding user response：

You might GNU AWK for this as follows, let file.txt content be

235.67.89.65
23.66.34.90
12.34.98.45
12.45.77.100

then

awk '{print $0 ":8080"}' file.txt

output

235.67.89.65:8080
23.66.34.90:8080
12.34.98.45:8080
12.45.77.100:8080

Explanation: for each line do print whole line ($0) concatenated with :8080.

(tested in gawk 4.2.1)
