I want to perform the title-named action under linux command-line(several ca bash script will also do). the command I tried is:
sed 's/href="([^"])"/$1/g' page.html > list.lst
but obviously it failed.
To be precise, here is my input:
<link rel="stylesheet" type="text/css" href="style/css/colors.css" />
<link rel="stylesheet" type="text/css" href="style/css/global.css" />
<link rel="stylesheet" type="text/css" href="style/css/icons.css" />
the output I want would be a comma-separated or space-separated list of all matches in the input file:
style/css/colors.css,style/css/global.css,style/css/icons.css
I think I got the right expression: href="([^"]*)"
but I have no clue how to perform this. sed would do a search/replace which is not exactly what I want.( to the contrary, I only need to keep matches and throw the rest away, and not to replace them )
