"\e" is the shorthand for typing the escape character, you will probably
want to escape the backslash like so: `\\`. It looks like you may be trying
to create a command string, but you've used string delimiters (") instead
of cmd delimiters (`). Julia always uses the entire literal string (include
embedded newlines) until the closing " character). Because some characters
(like a newline) cannot be directly printed, Julia shows it as \n when
representing it in "" quotes to display the variable. Similarly, it prints
a literal " as \" so that you can tell that the " is part of the string and
not indicating the termination of the string.On Wed, Aug 26, 2015 at 7:00 PM J Luis <[email protected]> wrote: > I need to build a command as a string to pass to an external program > (GMT), so I started to build it this way > > julia> ps = "V:\example_23.ps"; > > julia> name="Rome"; > > julia> "pscoast -Rg -JH90/9i -Glightgreen -Sblue -A1000 -Dc -Bg30 > -B+t\"Distances from " * name * " to the World\" -K -Wthinnest > > " * ps > > "pscoast -Rg -JH90/9i -Glightgreen -Sblue -A1000 -Dc -Bg30\n > -B+t\"Distances from Rome to the World\" -K -Wthinnest > V:\example_23.ps" > > > Two things here.
