Hello,
I am struggling to find a solution to the following apparently simple
problem, so any help would be much appreciated.
Here is a simple example of what I'm trying to do.
>From the console of a linux machine running Fedora-12, if I do
echo "AB" > file
FILE=file
sed "s/AB/12/" $FILE
I get, as expected,
12
I can also do
COMMAND="sed s/AB/12/ $FILE"
$COMMAND
and again I get
12
So far so good. If, however, I now introduce a space with
echo "A B" > file
I'd like to find the setting for COMMAND which is equivalent to
sed "s/A B/1 2/" $FILE
1 2
I've tried a number of obvious variations, but I can't get any to
work, for example,
COMMAND="sed s/A B/1 2/ $FILE"
$COMMAND
sed: -e expression #1, char 3: unterminated `s' command
COMMAND="sed \"s/A B/1 2/\" $FILE"
$COMMAND
sed: -e expression #1, char 1: unknown command: `"'
COMMAND='sed "s/A B/1 2/" $FILE'
$COMMAND
sed: -e expression #1, char 1: unknown command: `"'
COMMAND="sed 's/A B/1 2/' $FILE"
$COMMAND
sed: -e expression #1, char 1: unknown command: `''
Thanks,
Paul
