Self-extracting archive

<< < (2/5) > >>

H_TeXMeX_H:
Well I wrote a script that makes self-extracting and removing packages (I've tried to make it as safe as possible so it only deletes stuff you actually installed with the packaging system and only in /usr/local) I also added an extract feature so you can extract the archive inside to anywhere you want.


--- Code: ---#!/bin/sh

if [ -a /tmp/Sirx ]; then
 rm -rf /tmp/Sirx
fi

mkdir /tmp/Sirx
mkdir /tmp/Sirx/local

echo "Build package from [s]ource or from [b]inary? "
read pack

if [ "$pack" == "s" ]; then
 mkdir /tmp/Sirx/source
 echo "Path to folder containing configure and/or Makefile? "
 read inputsource
 cd "$inputsource"
 cp -r * /tmp/Sirx/source
 cd /tmp/Sirx/source
 if [ -a configure ]; then
  if ./configure --prefix=/usr/local ; then
   echo "configure complete"
  else
   echo "!configure failed!"
   read dummy
   exit 1
  fi
 fi
 if make ; then
  echo "make complete"
 else
  echo "!make failed!"
  read dummy
  exit 1
 fi
 if make prefix=/tmp/Sirx/local install ; then
  echo "make install complete"
 else
  echo "!make install failed!"
  read dummy
  exit 1
 fi
elif [ "$pack" == "b" ]; then
 echo "Path to folder containing binary? "
 read inputbinary
 cd "$inputbinary"
 cp -r * /tmp/Sirx/local
else
 echo "!Incorrect input!"
 read dummy
 exit 1
fi

cd /tmp/Sirx/local

echo "Name of output package file? "
read outputfilename

tar -czf /tmp/Sirx/"$outputfilename".tar.gz *

find -type f > /tmp/Sirx/remove.txt

cd /tmp/Sirx/
sed 's/\./\/usr\/local/' remove.txt > removefixed.txt

echo "#!/bin/sh" > header.sh
echo SKIP=\`awk \'\/\^__ARCHIVE_FOLLOWS__\/ { print NR + 1\; exit 0\; }\' \$0\` >> header.sh
echo \echo \""$outputfilename"\" >> header.sh
echo \echo \"Select: \[i\]nstall, \[r\]emove, e\[x\]tract, or any other key to quit\? \" >> header.sh
echo "read switch" >> header.sh
echo \if  \[ \"\$switch\" == \"i\" \]\; \then >> header.sh
echo \echo \"Installing . . .\" >> header.sh
echo \tail +\$SKIP \$0 \| tar xz -C \/usr\/local >> header.sh
echo \echo \"Done\" >> header.sh
echo \elif \[ \"\$switch\" == \"r\" \]\; \then >> header.sh
echo \echo \"Removing . . .\" >> header.sh
while read line
do
 echo rm "$line" >> header.sh
done < removefixed.txt
echo \echo \"Done\" >> header.sh
echo \elif \[ \"\$switch\" == \"x\" \]\; \then >> header.sh
echo \echo \"Extract directory\? \" >> header.sh
echo "read extract" >> header.sh

echo "else" >> header.sh
echo "exit 1" >> header.sh
echo "fi" >> header.sh
echo "exit 0" >> header.sh
echo "__ARCHIVE_FOLLOWS__" >> header.sh

cat header.sh "$outputfilename".tar.gz > $HOME/"$outputfilename".sh

cd $HOME
echo "Finished, check your home folder . . . press [Enter] to quit"
read dummy
rm -rf /tmp/Sirx
exit 0

I also put it up on my site along with the home-made man page for it and further info on how to use it properly.

ReggieMicheals:
What UNIX needs is less irritating makefiles and more windows-like installers/uninstallers with actual binaries if the home market is going to accept UNIX OSes. Its a small step, but it's a step nonetheless...

H_TeXMeX_H:
I like binaries ... but not Window$ installers ... after switching to Linux, I realized how retarded the Window$ installers really are. They all go something like this if I remember correctly:

Double-click the exe file ... it loads after 1-2 min
"Blah, Blah, Blah, Blah, Blah, Blah ... click next" -> you click next
"Do you accept this 200 page EULA ?" Only option: Yes -> you click yes
click next 5 times
"Install to /Program File$ ?" -> yes
click next 5 more times
"Installing" ...
30-45 minutes later ... Done
And you goto the next installer and do it over again !!!

You wonder how efficient this system really is ... not at all efficient. I was really surprised by how easily and quickly RPMS install compared to the Window$ way. With rpm it takes like 2 steps max and installs nearly instantly. I'm never going back to Window$ ... or any of their inefficient bullshit.

If you want Linux installers try Loki ... too bad they went out of business.

Aloone_Jonez:
It depends alot on the installer, I haven't had any trouble with OpenOffice, Opera and Firefox but some of the shareware shitware used to give me that kind of grief.

Yeah, you do have to wonder what moron came up with the idea. What would be better is something along the lines of a self extracting zip file with a self deletion program in the installed directory.
