bash profile

As we know, suse does not create .bash_profile when add a new user. But redhat does.

But if our program need some command from the profile, it is an issue.

 

So, we need to add this file when add the new user in script. And we need think about update the program.

 

if [ -f /etc/SuSE-release ] ; then #if the os is suse
      if [ ! -f %rvhome/.bash_profile ] ; then #if the file is not exist
        touch %rvhome/.bash_profile
        echo 'PATH=$PATH:$HOME/bin' >> %rvhome/.bash_profile
        echo 'export PATH' >> %rvhome/.bash_profile
        echo 'unset USERNAME' >> %rvhome/.bash_profile
    else #if the file is exist
      grep 'export PATH' %rvhome/.bash_profile > /dev/null #test the file has the key word 
      if [ $? -eq 0 ] ; then #$? means last output [0:exist 1:not exist]
            #echo 'export PATH is Exist.'
      else
            echo '' >> %rvhome/.bash_profile #if the file is empty, it needed add first line

            #search the key word line number
            LINE=`grep -n 'PATH=' %rvhome/.bash_profile | awk -F : '{print $1}'`

            ((LINE++)) #plus the line number
            sed -i "$LINE i export PATH" %rvhome/.bash_profile #insert string at the line into the file
            ((LINE++))
            sed -i "$LINE i unset USERNAME" %rvhome/.bash_profile
            sed -i "1 i PATH=\$PATH:$HOME/bin" %rvhome/.bash_profile
      fi
   fi

fi

 

result:

PATH=$PATH:$HOME/bin

export PATH
unset USERNAME
