Adding directory to path

[Phifer]

I did get it working and thanks again for your patience. Since I got this system in December I am learning a lot about Linux and command line albeit slowly.

You are progressing very well indeed. You seem very well suited to this technology, and to Forums participation. You have provided information when requested, and you have obviously done your homework before asking questions. It is a pleasure to help you. Please continue to ask questions. (I'm no smarter than you are, I've simply been doing this longer).

Everything in this thread and in the wiki link is totally outdated.

Modifications in /etc/profile doesn't survive to a reboot.
/etc/init.d/Optware.sh doesn't exist.

The wiki indicates how to install on v3.8, we are on v4.3.

I do undesrtand the security issues with this, but seriuosly : I almost got locked away my own device by just changing my shell to zsh in /etc/password.
After the next reboot link to /usr/bin got wiped out (so /usr/bin/zsh did goes away) and every .zsh* config file got wiped out from /root.
...

And of course nothing is documented anywhere.
Don't get me wrong: that last point is what that is annoying me the most !

Because you do not use /root:

Code: Select all

admin:x:0:0:administrator:/share/homes/admin:/bin/bash
zadmin:x:0:0:administrator:/share/homes/admin:/opt/bin/zsh

So... here what I think is the easier way to solve the problem:

1. install Entware
2. edit /opt/etc/profile and add something like this:

Code: Select all

# If running interactively, then:
if [ "$PS1" ]; then

    if [ "$BASH" ]; then
        export PS1="[\u@\h \W]\\$ "
    else
      if [ "`id -u`" -eq 0 ]; then
        export PS1='# '
      else
        export PS1='$ '
      fi
    fi

    export USER=`id -un`
    export LOGNAME=$USER
    export HOSTNAME=`/bin/hostname`
    export HISTSIZE=10000
    export HISTFILESIZE=10000
    export HISTFILE=/share/homes/admin/.bash_history ### IMPORTANT: This permit you to change the history Path were .bash_history will be saved.
    export PAGER='/bin/more '
    export EDITOR='/bin/vi'
    export INPUTRC=/etc/inputrc
    export DMALLOC_OPTIONS=debug=0x34f47d83,inter=100,log=logfile
    export LS_COLORS='no=00:fi=00:di=01;34:ln=01;36:pi=40;33:so=01;35:do=01;35:bd=40;33;01:cd=40;33;01:or=40;31;01:ex=01;32:*.tar=01;31:*.tgz=01;31:*.arj=01;31:*.taz=01;
31:*.lzh=01;31:*.zip=01;31:*.z=01;31:*.Z=01;31:*.gz=01;31:*.bz2=01;31:*.deb=01;31:*.rpm=01;31:*.jar=01;31:*.jpg=01;35:*.jpeg=01;35:*.png=01;35:*.gif=01;35:*.bmp=01;35:*.
pbm=01;35:*.pgm=01;35:*.ppm=01;35:*.tga=01;35:*.xbm=01;35:*.xpm=01;35:*.tif=01;35:*.tiff=01;35:*.mpg=01;35:*.mpeg=01;35:*.avi=01;35:*.fli=01;35:*.gl=01;35:*.dl=01;35:*.x

    ### Some aliases
    alias ps2='ps facux '
    alias ps1='ps faxo "%U %t %p %a" '
    alias af='ps af'
    alias cls='clear'
    alias ll='/bin/ls -laFh'
    alias ls='/bin/ls -F'
    alias df='df -h'
    alias indent='indent -bad -bap -bbo -nbc -br -brs -c33 -cd33 -ncdb -ce -ci4 -cli0 -cp33 -cs -d0 -di1 -nfc1 -nfca -hnl -i4 -ip0 -l75 -lp -npcs -npsl -nsc -nsob -nss -
ts4 '
    #alias bc='bc -l'
    alias minicom='minicom -c on'
    alias calc='calc -Cd '
    alias bc='calc -Cd '
fi;

3. edit /opt/Entware-ng.sh
a. change:

Code: Select all

# adding opkg apps into system path ...
/bin/cat /root/.profile | /bin/grep "source" 1>>/dev/null 2>>/dev/null
[ $? -ne 0 ] && /bin/echo "source /opt/etc/profile" > /root/.bash_profile

with:

Code: Select all

# adding opkg apps into system path ...
        /bin/cat /root/.bash_profile | /bin/grep "source" 1>>/dev/null 2>>/dev/null
        [ $? -ne 0 ] && /bin/echo "source /opt/etc/profile" > /root/.bash_profile

b. change:

Code: Select all

  stop)
        /bin/echo "Disable Entware-ng/opkg"
        /opt/etc/init.d/rc.unslung stop
        /bin/sed -i '/source \/opt\/etc\/profile/d' /root/.profile
        /bin/sync
        /bin/sleep 1
        ;;

with:

Code: Select all

  stop)
        /bin/echo "Disable Entware-ng/opkg"
        /opt/etc/init.d/rc.unslung stop
        /bin/sed -i '/source \/opt\/etc\/profile/d' /root/.bash_profile
        /bin/sync
        /bin/sleep 1
        ;;

4. Done

!!! Important as comprehension:

in /root there are a lot of hidden files that are always overwritten when QNAP is restarted, Like:
.bash_history
.bash_logout
.bash_profile
.bashrc
.profile

every restart this files are recreated the point is that if .bash_profile is there it will be read at first and .profile will not be read anymore.
When Entware-ng.sh is started at the boot process it create the necessary thing in .bash_profile that will be sourced in a interactive login shell.

From now on the history and opkg PATH will be kept.

I hope it was helpful.

I realise this is an old thread. However I have a related question. I have modified the scripts so that /etc/profile get updated everytime I boot up the NAS and login via SSH. The PATH is exactly how I need it when I log in via SSH. However job that are running on the crontab don't appear to be using my modified path. The issue here is that there are two python installations, one that comes as part of the firmware - which is very old and doesn't have a lot of modules included. The Python that is installed via the App Manager is fine but without setting the PATH, my scripts can't use it. So I am stuck.

How do I set the PATH for the system and the non interactive users?

My original issue is listed here.

Crontab scripts do not use any of those settings for the path, since it is not interactive. Whatever script is run by crontab must contain the path you want set, or the script can source a file that contains the desired path.

I have modified the scripts so that /etc/profile get updated everytime I boot up the NAS and login via SSH. The PATH is exactly how I need it when I log in via SSH.

Please can you explain exactly how you did this so i don't have to run

Code: Select all

export PATH=/opt/bin:/opt/sbin:$PATH

every time I start an SSH session?

Thanks
