script to convert words into links
hi,

i need some help.
i have to write a unix shell script that opens a file with a list of words and prints another file with a list of links.
something like this:

Input:

FILE 1:
Red
Green
Blue

Output:

FILE2:
http://www.google.com/search?hl=en&q=Red
http://www.google.com/search?hl=en&q=Green
http://www.google.com/search?hl=en&q=Blue]Blue

How would you do this ?

A solution with sed :
Code:
sed 's§^§http://www.google.com/search?hl=en&q=§' FILE1 > FIL2

Code:
sed 's%^%http://www.google.com/search?q=%'

I don't think you need the hl=en parameter.

PS. Might be better to use code tags for raw http links.

Jean-Pierre's solution has the problem that the & needs to be backslash-escaped. Seems we posted at exactly the same time.

A solution with awk :
Code:
awk '{printf "http://www.google.com/search?hl=en&q="}1' words_file > links_file

thank you.

that would be the core of the script , but how would you put the loop to read the words one by one and print them out in the other file ?
