Full Discussion: check the directory exist
Top Forums Shell Programming and Scripting check the directory exist Post 77097 by mbb on Monday 4th of July 2005 09:59:17 AM

FYI ust:

if [ -d $dir ]
then
...
fi

is actually using the 'test' command. To find out what you can do with the test command then type: 'man test'

You may also write the above as:

if test -d $dir
then
...
fi

or even use the test command on the comand line thus:

>test -d $dir
>echo $?

Also I would recommend shell variables to be quoted in this context:

if [ -d "$dir" ] ...

to avoid any command line errors with the test command!

i.e. if $dir were emtpy and you did if [ -d $dir ], then you would really be running: 'test -d' and the test command would complain.

Hope this helps.

NAME
ipescript - Run an Ipe script (written in Lua) SYNOPSIS
ipescript script { arguments } DESCRIPTION
ipescript runs an Ipe script written in Lua. The Ipe bindings are automatically available in the script. Ipescript looks for the script in any of the script directories. The script argument should not contain the .lua extension. ENVIRONMENT VARIABLES
ipescript respects the following environment variables: IPELATEXDIR the directory where ipetoipe runs Pdflatex. IPESCRIPTS a list of directories where Ipescript will look for scripts. When this variable is not set, Ipe searches first the current directory, then ~/.ipe/scripts, and finally the system-wide Ipe script directory. When this variable is set, it should contain a list of directories, separated by semicolons. A single under- score is replaced by the system-wide Ipe script directory. IPEDEBUG set this to 1 for debugging output from ipescript. AUTHOR
Otfried Cheong REPORTING BUGS
Please report bugs using Ipe bugzilla at http://ipe7.sourceforge.net/bugzilla.html SEE ALSO
Ipe is documented fully in The Ipe Manual, which is available online at http://ipe7.sourceforge.net/manual/manual.html . August 28, 2011 IPESCRIPT(1)
