We often need to execute linux shell command from our groovy code. What I had to do in my project was to resize the image saved on file system.<\/p>\n
I was doing something like :<\/p>\n
[java]String command = "convert -adaptive-resize ${width}x${height}! ${sourceFilePath} ${destinationFilePath}"
\nProcess process=command.execute()
\nprocess.waitFor()
\n[\/java]<\/p>\n
The above code makes a new image file with specified width and height of image. The problem I encountered was that the above code doesnot work for files having spaces in their name e.g. file name “new house.jpg”
\n
\nThen by googling I found ProcessBuilder which is a utility class that interact with OS from java program and create OS processes.<\/p>\n
[java]ProcessBuilder pb = new ProcessBuilder("convert", "-adaptive-resize", "${width}x${height}!", sourceFilePath, destinationFilePath); We often need to execute linux shell command from our groovy code.

\nIt works seemlessly!!!
