bash script problem
hi
I am writing a bash script that uses dialog to get user input an diplay messages to user. I have a small problem
dialog --inputbox "blabla" 20 50 2> /tmp/output
VAR="'cat /tmp/output'"
mkdir $VAR
the code below requests user for a directory path to be created.
But, if the user uses something like this
~/anydir
mkdir fails! "~ no such file or directory". In other words, if user uses ~/ instead of /home/username mkdir fails.
Can anyone help me?
Thanks...

I'm having problems with bash scripts. If a bash script is called with no arguments, I always get "PHIST=!" as the first argument (i.e. this is what $1 equals). Why? Where does this come from, and how can I fix it? Nothing in the bash man pages refer to this mysterious default argument. (2 Replies)

mkpath_np
mkpath_np(3) BSD Library Functions Manual mkpath_np(3)
NAME
mkpath_np -- Auxiliary routine for efficiently creating paths
SYNOPSIS
#include <unistd.h>
int
mkpath_np(const char * path, mode_t omode);
DESCRIPTION
This routine allows the caller to create a path, including intermediate directories. It is equivalent to calling mkdir(1) with the -p com-
mand line argument.
Intermediate directories are created with permission bits of rwxrwxrwx (0777) as modified by the current umask, plus write and search permis-
sion for the owner.
The leaf directory is created with permission bits of omode as modified by the current umask.
RETURN VALUES
A 0 return value indicates success. If an error occurs, the return value is a non-zero error code. Note that EEXIST is returned iff the
leaf directory already exists and is a directory, so under certain circumstances, this error value may not indicate a failure state.
This routine does NOT modify errno.
ERRORS
Any error code that can be returned by mkdir(2) can be returned by mkpath_np(), but mkpath_np() will return the error code rather than set-
ting errno.
[ENOTDIR] A component of the path is not a directory (in contrast to mkdir(2) which returns this based on the path prefix rather
than the path).
[EEXIST] The path already exists and is a directory.
HISTORY
This function first appeared in iOS 5.0.
