[9fans] name=`{cat foo} - Plan9
This is a discussion on [9fans] name=`{cat foo} - Plan9 ; Hello.
I have a problem that I feel difficult to solve.
Assume a filename is in a file "foo"
Then rc script
name=`{cat foo}
will mostly succeed in copying the filename to "name" but for some

For example:

Hello.
I have a problem that I feel difficult to solve.
Assume a filename is in a file "foo"
Then rc script
name=`{cat foo}
will mostly succeed in copying the filename to "name" but for some
exceptions.
For example:
echo 'abc def' >foo
name=`{cat foo}
whatis name
The output result is:
name=(abc def)
I want to have a shell variable such as:
name='abc def'
How to do?

You could start by reading the paper or the man page.
for 'abc def':
ifs='
' { name = `{cat foo} }
for 'abc def
', or 'abc def' if you'd used 'echo -n':
ifs=() { name = `{cat foo} }
