I'm writing a command-line application and I want to search through lots of text files for a string. Instead of writing the python code to do this, I want to use grep.
This is the command I want to run: $ grep -l foo dir In other words, I want to list all files in the directory dir that contain the string "foo". I'm looking for the "one obvious way to do it" and instead I found no consensus. I could os.popen, commands.getstatusoutput, the subprocess module, backticks, etc. As of May 2009, what is the recommended way to run an external process like grep and capture STDOUT and the error code?
