Post by: Mark David on March 16, 2007, 01:36:21 PM

Determine if a file is writable by a Bourne script user

From a Bourne shell script (sh, ksh, bash, ...), it is possible to test if a file exists and is writable by the user running the script.

Code:

if [ -w testfile ] 
then 
  echo testfile is writable! 
else 
  echo non writable...
