bash Problem with "sed" command
 

Hi there,
i want to search and replace strings with sed and normally its no prob but now i am at a point where i dont know further perhaps u could help me.
i want to cat a file and replace certain strings with "html" code but with the special sings in html my bash doesnt take the string as i like.
here is the cat'ed file:
#-------------cat.file-------------------
70
0
0
0
0
70
70
0
0
0
70
#--------------end---------------------

i tried in this one to replace the 70's with the "<img border="0" src="Warning.gif" width="126" height="26"></p>" html code

so i took this command:
cat cat.file | sed s/70/"<img border="0" src="Warning.gif" width="126" height="26"></p>"/g

but no chance he won't replace.....

PLEASE help me
:scratch:

hi,

you need to to escape characters ", >, < and / so your shell will bypass them.

how do i escape special characters?


Sorry i just did not realize that u postet the new code there ... damn where is my brain today...need more coffee :jawa:



Thanks for your help it works perfectly :D
But one question is still there
sed s/70/"<img border=\"0\" src=\"Warning.gif\" width=\"126\" width=\"26\"\>\<\/p\>"/g
why dont i have to uncomment the first < sign ???? doesnt this one try to pipe the word image into something? (Sorry but i'am a :newbie: )

you just need to escape special characters. I've edited the code to be "more correct"

everything between " and " is treated as one string by shell, when you want another " in the string you have to escape it.
also you have to escape / in the string because sed thinks it's the end of the search part in s/
