Changing path in many files
I have many html files in a directory tree and want to change the a path declaration within the files.

Files will look as below

I want to remove "geopdf/" so I get as example

Code:
href=../../../geo1937/geo02n01/geo0201r00010016.pdf

rather than keeping the entry as

Code:
href=../../../geopdf/geo1937/geo02n01/geo0201r00010016.pdf

I have tried the following awk command, the result being incorrect

Code:
awk -v s="..geopdf/" -v d="/" '{gsub(s,d); print}' /home/chrisd/Desktop/geo1937/geo02n04.html

Code:
<html>
<head>
<title>Vol. 2, No. 1 - 1937</title>
<script language=javascript>

<!--
function goback() {
        history.back();
}
//-->

</script>

This command seems to work. Can someone confirm this will work on all my files please.

Code:
awk -v s="geopdf/" -v d="" '{gsub(s,d); print}' /home/chrisd/Desktop/geo1937/geo02n01.html

It would be safer to use:
Code:
awk -v s="/geopdf/" -v d="/" '{gsub(s,d); print}' /home/chrisd/Desktop/geo1937/geo02n01.html

in case other directory names ending in "geopdf" could appear in your data.
