Shell script to replace a variable in a HTML document
Using awk
[jaypal:~/Temp] cat html.sh #!/bin/bashauthor="Github INC."name="Github"description="social coding"awk '{sub(/\$name/,name);sub(/\$author/,author);sub(/\$description/,description);}1' name="$name" author="$author" description="$description" inputfileUsing sed
[jaypal:~/Temp] cat html1.sh #!/bin/bashauthor="Github INC."name="Github"description="social coding"sed -e '/\$name/s//"$name"/' -e '/\$description/s//"$description"/' -e '/\$author/s//"$author"/' inputfile
see the test (with awk) below: actually sed should work as well.
