BACKTRACK 5 LOG IN ERROR

LOGIN  ERROR  SOLUTION  FOR  BACKTRACK 5

Some of us face this very unusual error while logging on to the Backtrack. The following message is shown in this error.

"-bash: /etc/profile: line 1: syntax error near unexpected token".

So when we go to error file location inside the file there is the next code :

ERROR CODE :


n# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))\n

# and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).\n\nif

[ -d /etc/profile.d ]; then\nfor i in /etc/profile.d/*.sh; do\nif [ -r $i ];

then\n. $i\nfi\ndone\nunset i\nfi\n\nif [ "$PS1" ]; then\nif [ "$BASH" ];

then\nPS1=u@h:w$ \nif [ -f /etc/bash.bashrc ];

then\n.

/etc/bash.bashrc\nfi\nelse\nif [ "id -u" -eq 0 ];

then\nPS1=# \nelse\nPS1=$ \nfi\nfi\nfi\n\numask

022\nPT5HOME=/opt/pt\nexport PT5HOME
 

SOLUTION :

Fix the formatting, in the code replace  "/n"  by actual Newlines and remove the spurious 'n' at the begning, then the code works properly. Thus new code will look like this. 

# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))

# and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).

if [ -d /etc/profile.d ]; then

  for i in /etc/profile.d/*.sh; do

    if [ -r "$i" ]; then

      . "$i"

 fi

  done

  unset i

fi

if [ -n "$PS1" ]; then

  if [ -n "$BASH" ]; then

    PS1='u@h:w$ '

    if [ -f /etc/bash.bashrc ]; then

      . /etc/bash.bashrc

    fi

  else

    if [ "`id -u`" -eq 0 ]; then

      PS1='# '

    else

      PS1='$ '

    fi

  fi

fi

umask 022

PT5HOME=/opt/pt

export PT5HOME 

Now sava this file and reboot your system to apply the change. That's it......!!
