[aur-general] postinstall script and local user directory
Hello, I need a little help with a postinstall script, the script should make automatically a few postinstall steps on the LMD installation, qhat the script should make it's to detect if a directory called .LMD on the home directory exists, if it exists, it shows an informative message, if it doesn't exist it makes it. All right the problem is: It acts over the root directory, and I want it to act over the user normal directory (/home/'user') For you tu understand what I mean, this is the code: http://pastebin.com/57L2Jt2P <- With that it looks for a directory called "~", not "home" directory I als otried with an array, and it was here when it used root like home directory, and not the local user directory: http://pastebin.com/TCh94dC9 I want the script to do the same that it makes with the second paste bin, but not in root, it should be, in my pc for example, on /home/jorge... Thanks in advance

Hi Jorge, Try "/home/$USER" instead of "~". -- `--[ Myles ]

i suggest installing a script doing what you want to do in $HOME directory and print out an instruction in post_install function to remind the user to run that script as normal user without sudo. inside the script, $HOME can be used, or ~ too. regards,

Thanks Auguste, I'd like to do it all in the postinstall even though, I'll try a little changes on it and I'll see what can I do and if I see it doesn't works... I'll keep that on account Good Idea, I wasn't thought about that ;)

Since your first post, I was not comfortable having a install script looking for a normal user's home folder, because you can always find yourself in the situation that a user might be added after LMD is installed. (not being harsh, just not a good idea, IMO) So, I came up with the idea of applying a patch in the 'ldm' script. With this patch, 'lmd' would verify if the user have '~/.LMD' everytime, right before starting the gtkdialog. See my diff: --- src/usr/local/bin/lmd 2011-07-03 17:19:24.000000000 -0300 +++ pkg/usr/bin/lmd 2012-05-21 22:07:06.587084106 -0300 @@ -323,6 +323,7 @@ if [ -z $1 ]; then + [ ! -d ~/.LMD ] && lmd -reconf gtkdialog --program=MAIN_DIALOG fi echo $1 I added the following line the PKGBUILD, after installing lmd to '$pkgdir': sed -e '325s#then#then\n\t[ ! -d ~/.LMD ] \&\& lmd -reconf#' -i "${pkgdir}"/usr/bin/lmd which just replace in line 325 the "then", adding one more line with the command command you provided.

I added the following line the PKGBUILD, after installing lmd to '$pkgdir':

Mmm yes it helps, I know what you mean, adding a line on the own lmd binary script that checks if .LMD already exists... any time you run lmd an for any user ;) Not bad :D but... if fear I don't know so sed "command", so I can't comprehend where are you exactly telling me that I should put that or... well :S sorry, could you explain it a little more :S My bigest thanks friend

If you're not comfortable with sed, you can always create a patch using 'diff -u foo1 bar2 > foo-bar.patch' and add to source=() ... But since we are here: My sed command executes an expression in an input text. The input text is from the file 'lmd'. I also added the flag '-i' so the output of this command will not go to stdout, but directly to the input file. So, it will not just read the file, but alter/write too. The expression structure is basically 'A#B#C#', where #s are delimiters; A is a specific line number that sed will look and replace; B is the regexp to look (and to be replaced) in that line in A; and C is the replacement regexp that I want to replace B. Please note that '\n' is a newline character and '\t' is a tab character. So, as I mentioned before, I replaced the string 'then' in line 325 with the new line/command you provided. 'sed' can do much more than that. Man page and google can help a lot. Cheers, Rafael Ferreira

Oh, ok, yeah I read a bit on the man page and o a webpage, but it's too large, it has so many functions. Eitherway, I understand what you said now. Then, on my PKGBUILD, I should modify the package()... in the next way?: package() { cd "${srcdir}" tar xf data.tar.gz mkdir -p "${pkgdir}/usr/" cp -r "${srcdir}/./usr/local/bin" "${pkgdir}/usr/bin" cp -r "${srcdir}/./usr/share" "${pkgdir}/usr/share" sed -e '325s#then#then\n\t[ ! -d ~/.LMD ] \&\& lmd -reconf#' -i "${pkgdir}"/usr/bin/lmd chmod +x "${pkgdir}/usr/bin"/* sed 's|usr/local|usr|' -i "${pkgdir}/usr/bin"/* sed 's|usr/local|usr|' -i "${pkgdir}/usr/share/applications/LMD.desktop" sed 's|usr/local|usr|' -i "${pkgdir}/usr/share/doc/linux-manga-downloader/copyright" sed 's|usr/local|usr|' -i "${pkgdir}/usr/share/icons/pen.png" sed 's|usr/local|usr|' -i "${pkgdir}/usr/share/lmd/langs/ca_ES" sed 's|usr/local|usr|' -i "${pkgdir}/usr/share/lmd/langs/es_ES" }

Looks good. Try to build the package and then verify if pkg/usr/bin/lmd has the command added with sed. Case yes, then you're good to go. Rafael Ferreira

ok. in this case, i suggest you make a wrapper script that 1. checks the content in user's $HOME directory, 2. does whatever is necessary, 3. runs the actual program.
in this case, what you have done is totally transparent to the user and every user on the system can use that application.
best regards,
It doesn't worked :S I'll see what to do... maybe it's because of I have to change something else on the PKGBUILD Auguste... It's a good idea, doing it like a patch, it'll be easier, but I don't like adding patches... even I'll do a patch if I can't do it on another way ;)
