Since my python knowledge is limimted, I've challenged myself to learn as much as possible to help me with my carrere. I'm currently trying to convert a shell script to python, just to give myself a task. There is one section of the script that I'm having issues converting and that is this line:
Code:
sha256 -C SHA256 image.iso
which basically checks the checksum of "image.iso" against a textfile called SHA256, which contains the correct checksum.
A sample of "SHA256" is below (ignore the same checksum everywhere, it's just for example purposes):
import hashlib
workdir = '/tmp'
iso_image = 'image.iso'
def check_sha256(block_size=65536):
sha256 = hashlib.sha256()
with open(workdir + "/" + iso_name, 'rb') as f:
for block in iter(lambda: f.read(block_size), b''):
sha256.update(block)
computed_sum = print(sha256.hexdigest())
sha256sum
but I'm stuck as to how I should go about picking up the correct line from the "SHA256" file and then compare the hash (I guess I can do it with "if variable in" or something.
The following find command works on the Korn Shell command line:
find . \( ! -name . -prune \) -type f -name "*.txt" -mtime +100
In the particular directory I'm in, the above find will list correctly the three text files that exist that haven't been modified in over 100 days:

Hi,
I don't know hot to make this command work:
ls -laR | grep "^-" | awk '{print $9}'| grep "$.txt"
It should return the list of file .txt
It's important to search .txt at the end of the line, becouse some file name have "txt" in their name but have other extensions (13 Replies)
I have many Gaussian output files, which contain a string start from "HF=" but follws the different values. I'm trying to get this exact string from these txt files.

renpy
renpy(6) Games renpy(6)NAME
renpy - engine for creating visual novels
SYNOPSIS
renpy [path to the script directory]
DESCRIPTION
Ren'Py is a programming language and runtime, intended to ease the creation of visual-novel type games. It contains features that make it
easy to display thoughts, dialogue, and menus; to display images to the user; to write game logic; and to support the saving and loading of
games.
Ren'Py tries to be like an executable script, allowing you to get a working game without much more effort than is required to type the game
script into the computer.
Ren'Py is implemented on top of python, and that python heritage shows through in many places. Many Ren'Py statements allow python expres-
sions to be used, and there are also Ren'Py statements that allow for the execution of arbitrary python code. Many of the less-used fea-
tures of Ren'Py are exposed to the user by way of python. By only requiring use of the simplest features of python, it's hoped that Ren'Py
will be usable by all game authors.
USAGE
If you run the program without any arguments, zou will get an interactive launcher from where you can select, run and work different
projects.
For running a script, you need to give the full path to the directory that contains the game you want to play.
For example: renpy /usr/share/games/renpy/demo/
To learn how to use the game interface, you should install and play renpy-demo.
FILES
The game data for each user is stored at ~/.renpy/ directory.
The scripts can be installed in the system bz placing them under /usr/share/games/renpy/ , but you can run any script in an arbitrarz
directory just by telling the path as the parameter to the game.
