#Description

jjcli is a python module that tries to simplify the creation of unix filters by importing:

• getopt (for command line options ans args)
• fileinput (for [files/stdin] arguments)
• re (regular expressions)
• csv (for csv and tsv inputs)
• urllib.request (to deal with input argumens that are url)
• subprocess

regular expressions

imports all functions from re.* Use re.I re.X re.S for regexp flags

subprocesses (qx, qxlines, qxsystem)

a=qx( "ls" ) for x in qxlines("find | grep '.jpg$'"): ... qxsystem("vim myfile")

execute command return its stdout

def qx(*x) : return subprocess.getoutput(x)

execute command return its stdout lines

def qxlines(*x) : return subprocess.getoutput(x).splitlines()

execute command -- system

def qxsystem(*x): subprocess.call(x,shell=True)
