tcsh script problem

nanxy · 08-19-2008, 10:22 AM

hi~ all ~ there is a script like this :

Code:

 set FilePrefix=${HdfFile:r}
 ${BinDir}/CloudStatsModis   ${InputDirectory}   ${FilePrefix}.class
${InputDirectory}/stats

CloudStatsModis is an executable file when I tried to run it .the file
prefix included the path of the file. And I just want to include the
file name not the path. How can I do that ?
Thank you

You need to add BinDir to the PATH.

I would recommend using bash or another borne style shell for scripting - csh style shells are a little limited IMO.

However, assuming you wish to continue with tcsh, the syntax to set the PATH will look something like this:

Code:

setenv PATH "${PATH}:${BinDir}"

You will then be able to use simply "CloudStatsModis" to run it.

Given the answer from matthewg42, I'm not sure about the sense of the original question anymore. I interpreted the problem as related to the value of the variable FilePrefix. Anyway, here is my answer: if you want to strip out the path from the FilePrefix variable you have to apply another modifier to HdfFile:

Code:

set FilePrefix=${HdfFile:r:t}

where t removes all leading pathname components, whereas r removes a filename extension. You can apply multiple modifiers simultaneously by preceding each of them with a colon.

I think I did not read the OP very carefully... hehe, always good to throw a spanner in the works that way.
