Unix sed substitute text with / in

Comment:

I have a file (file1.txt) that has the string 08/01/2004 in the middle of it. I need a script (sed?) to write all records from file1.txt to file3.text. I need a script (sed?) to substitute from file2.txt 09/01/2004 (that's the only thing in file2.txt for the 08/01/2004 in file1.txt before writing to file3.txt Thanks, Jim

sed "s%\([[:digit:]][[:digit:]]/\)\{2\}[[:digit:]]\{4\}%$(cat file2.txt)%" file1.txt > file3.txt

That would change all dates. To change just the 08/01/2004 string: sed "s%08/01/2004%$(cat file2.txt)%" file1.txt > file3.txt
