My bugfixed tcz sending script

[Akane]

Hi.

I made a script that sends the bugfixed(made by user) tcz by Python.
Please examine this. Request for comments.

Code: [Select]

#!/bin/sh -e
# restcz.sh
# Send a bugfixed tcz to the e-mail addr.
# 2012 Akane mail:i.can.speak.c.and.basic@gmail.com
# How to use:
# $ ./restcz.sh [tcz archive file]
# e.g.,$ ./restcz.sh gfortran.tar.gz.bfe
#
################################
# NOTICE. READ BEFORE RUNNING. #
#################################################
# The e-mail addr which is to send bugfixed tcz #
# is "tcesubmit _at_ gmail _dot_ com".          #
# So please subst it to the "to_addr" below.    #
#################################################

normalsmtp=\"smtp.anywhere.com\"
googlesmtp=\"smtp.gmail.com:587\"

yourgmailuser="getpass.getuser()"
yourgmailpasswd="getpass.getpass()"

# Uncomment these if needed.
#from_addr="you@anywhere.com"

# change _at and _dot_ before uncommenting
#to_addr="tcesubmit _at_ gmail _dot_ com"

if ! which python >/dev/null;then
echo install python.tcz first. >&2
exit 1
fi

usage(){
cat <<END >&2
$@.
Usage: $0 [file to mail]
END
exit 1
}

[ $# -ne 1 ] && usage invalid number of the argument
sendfile=$1
[ -e "$sendfile" ] || usage $sendfile does not exists
echo $sendfile | grep \.tar\.gz\.bfe >/dev/null || \
[ $0 = $sendfile ] || \
usage $sendfile is not a tcz archive

basesendfile=$(basename $sendfile)

subject="$(basename $sendfile .tar.gz.bfe).tcz update"

if [ -z "$to_addr" ];then
echo -n input the e-mail addr to send $sendfile:
read to_addr
fi

if [ -z "$from_addr" ];then
echo -n input your e-mail addr:
read from_addr
fi

echo input the body of the mail. press ^D to exit editing.
body=$(cat)

lessthem(){
less <<END
Things will be sent.
Subject: $subject
To: $to_addr
From: $from_addr
Attach: $sendfile
Message:
$body
END
}

while ! [ "$ans" = y ];do
lessthem
echo -n Is this OK? \(y,n,r\)
read ans
if [ "$ans" = n ];then
cat <<END
You chose n. Now exit.
Writing such data on this script is recommended.
It will be easy for you!

echo done. thank you for using this script. by Akane.


[bmarkus]

Why do you wrap the Python program into a shell script instead of having it as a Python script?

[Akane]

hello bmarkus.

The processes that is in the script can express as shell commands.
I think separating the shell script and python script to another file makes the treatment bother.

Thanks.

[bmarkus]

Why do you need the shells cript? It is just a bootstrap for the Python. I would drop shell and use only Python.

[Akane]

Thanks for your reply.

I will write two scripts using Python and Shell.
One is to send a mail,
and the other is to ask user and send the bugfixed tcz.

I have few times to fix it because I have to write a report.
Next script will be functional.

Please wait a few days.
