how does unix handle full path name with space and arguments

Question

How does unix handle full path name with space and arguments   In windows we quote the path and add the command-line arguments after  how is it in unix     c  foo folder with space foo exe  -help   update   I meant how do I recognize a path from the command line arguments

If the normal ways don t work  trying substituting spaces with  20   This worked for me when dealing with SSH and other domain-style commands like auto smb

You can quote the entire path as in windows or you can escape the spaces like in     foo  folder  with  space foo sh -help   Both ways will work

Also be careful with double-quotes -- on the Unix shell this expands variables   Some are obvious  like  foo and  t  but some are not  like  foo     For safety  use single-quotes

I would also like to point out that in case you are using command line arguments as part of a shell script   sh file   then within the script  you would need to enclose the argument in quotes  So if your command looks like   gt scriptName sh arg1 arg2   And arg1 is your path that has spaces  then within the shell script  you would need to refer to it as   arg1  instead of  arg1  Here are the details

You can quote if you like  or you can escape the spaces with a preceding    but most UNIX paths  Mac OS X aside  don t have spaces in them    Applications Image  Capture app Contents MacOS Image  Capture    Applications Image Capture app Contents MacOS Image Capture    Applications  Image Capture app  Contents MacOS  Image Capture    All refer to the same executable under Mac OS X   I m not sure what you mean about recognizing a path - if any of the above paths are passed as a parameter to a program the shell will put the entire string in one variable - you don t have to parse multiple arguments to get the entire path

Since spaces are used to separate command line arguments  they have to be escaped from the shell   This can be done with either a backslash    or quotes     path with spaces in it to a file  somecommand -spaced  option somecommand  -spaced option  somecommand  -spaced option    This is assuming you re running from a shell   If you re writing code  you can usually pass the arguments directly  avoiding the problem   Example in perl   Instead of doing   print  code sample   system  somecommand -spaced option     you can do  print  code sample   system  somecommand    -spaced option     Since when you pass the system   call a list  it doesn t break arguments on spaces like it does with a single argument call

You can either quote it like your Windows example above  or escape the spaces with backslashes      foo folder with space foo  --help   foo  folder  with  space foo --help
