terminal - BASH function for escaping spaces in filenames before opening them -


i've been trying write function bash profile quite time now. problem i'm trying overcome i'm provided file paths include spaces , it's pain having go through , escape spaces before try open in terminal.

e.g. file -> /volumes/company/illustrators/website front page design.ai

what i'm trying end '/volumes/company/illustrators/website\ front\ page\ design.ai' being opened terminal.

so far i've managed escape spaces out, error "the file ..... not exist."

my code far 

function opn { open "${1// /\\ }";}

any appreciated.

the important thing understand difference between syntax , literal data.

when done correctly, escaping syntax: it's read , discarded shell. is, when run

open "file spaces"

or

open file\ with\ spaces

or even

open file" "with\ spaces

...the quoting , escaping parsed , removed shell, , actual operating system call gets executed this:

execv("/usr/bin/open", "open", "file spaces")

note there aren't backslashes (or literal quotes) in syscall's arguments! if put literal backslashes in data, cause run:

/* c syntax, "\\" single-character backslash literal */ execv("/usr/bin/open", "open", "file\\ with\\ spaces")

...and unless there's file backslashes in name, doesn't work, giving "file not exist" error report.

so -- call open name in quotes:

open "$1"

...there's no need opn wrappper.
