The following won't work because it will uncomment lines I don't want
uncommented.
cat file|sed "s/^#//g"
The below won't work because I will not always know what word2 word3 word4
is.
sed -e 's/^#Word1 Word2 Word3 Word4/Word1 Word2 Word3 Word4/' file >
/tmp/file

Thanks for your reply Bill.
However, I find I wasn't very precise. I need to know how to find a string
associated
with one or more lines in a file and replace it with another string while
retaining everything
else in that line.
For example:
Find string: #Word1 Word2 Word3 Word4
Replace with: Word1 Word2 Word3 Word4
I am uncommenting a line in a file. So, I need to change the first word
with
another,
while retaining the rest of the line.

sed "s/A//g" wil replace all "A" characters with nothing. Hence delete
them.

Does anyone know of a way, using "sed" or "awk", to delete a single
character
or characters from a line within a file.
Thanks,
