>> , how to use ?

thanhVic · 02-05-2005, 03:07 AM

I have a file:

$ cat new
face.jpg
owl-face.jpg
man-face.jpg

normally, if we want to append a character or a file:

$ echo "anything.jpg" >> new

$ cat new
face.jpg
owl-face.jpg
man-face.jpg
anything

my question is how to append "anything" any where I want ;

face.jpg anything
owl-face.jpg
man-face.jpg
anything

or

face.jpg
anything owl-face.jpg
man-face.jpg
anything

thanks for helping,

i believe you'd use sed for this, but you'd have to specify what you mean by "anywhere"... like, perhaps you wanna insert the text after a certain line number, or maybe after a certain text pattern, etc...

just my two cents...

Well, I know how to do that with sed. But I wonder if there is any way to do it with bash?

My problem is I have a file "new"

$ cat new
face.jpg
owl-face.jpg
man-face.jpg

How I make this file become a html file ?
<html>
<body>
<table>
<tr><td><img src=face.jpg></td>
<tr><td><img src=owl-face.jpg></td>
<tr><td><img src=man-face.jpg></td>
</table>
</body>
</html>

bash only,
thanks,

if you already know how to do this with sed, then you have everything you need...

you can't do it "just with bash" as bash is just a shell and needs access to commands such as cat, grep, gawk, sed, etc. to be able to actually do stuff like this...

i see what you mean... well, i'd imagine you could use variables, so that when you echo the text the variables would be replaced by the actual filename, or something like that...

for example, let's say you make face.jpg equal to $jpg-001, then the line "<tr><td><img src=face.jpg></td>" could be printed like:

Code:

echo "<tr><td><img src=$jpg-001></td>"
