working on files with sed and pipe


Hello every one.

I try to do some thing with sed and | redirection i know it's possible but couldn't manage to done it.

Here is the problem:

I have 1 file template.htm whith a variable "XXX" in it. The file look like this:

Code:
<html>
<head>
<title>Download XXX on this page.</title>
</head>
<body>
bla bla XXX.zip
</body>
</html>
and a list of file in a test file let say list.txt this file look like this:
Code:
File1.zip.htm
File2.zip.htm
File3.zip.htm
and i'm looking for a command line to copie the file template.htm to each name file in list.txt File1.zip.htm, File2.zip.htm, etc... and replace the variable "XXX" by the name of the file without the extention .zip.html
so the File1.zip.htm would look like this:

Code:
<html>
<head>
<title>Download File1 on this page.</title>
</head>
<body>
bla bla File1.zip
</body>
</html>
I've try alot of thing with cat and sed command but no clue.
any lead would by very appreciate.

Thanks

This problem is just begging to use a HERE document.

Take a file named "filelist":
Code:
File1.zip.htm
File2.zip.htm
File3.zip.htm
And a bash script that contains your template in a HERE document:
Code:
#!/bin/bash
for file in $( cat filelist ); do
   cat >get${file%.zip.htm}.htm << EOF
<html>
<head>
<title>Download ${file%.zip.htm} on this page.</title>
</head>
<body>
bla bla ${file%.htm}
</body>
</html>
EOF
done
Because you chose filenames that didn't contain whitespace or meta characters,
I didn't have to change the IFS variable or double quote the variables.

Hello jschiwal

Thanks a million.

Just a quick modification...

Code:
#!/bin/bash
for file in $( cat filelist ); do
   cat >${file%.zip.htm}.htm << EOF
<html>
<head>
<title>Download ${file%.zip.htm} on this page.</title>
</head>
<body>
bla bla ${file%.htm}
</body>
</html>
EOF
done
I think it's better like this (i just remove the get after cat >) odevice you get an output for files name like getfile1.htm


Thanks again for this script, i was working on it sinse the beginning of this weekend.
so now i create a bite more than 1500 file in 20s using this script

The script was just a sample. Those were the files that I created when testing it out, so I assume yours will be different. I'm sure the final script won't use "bla bla" either!

I had mistakenly changed the name of the variable from file to flist for some stupid reason, and it took about 6 edits to find and correct the mistake.
