This script could be saved as /usr/local/bin/guess-it and then made executable:

# chmod a+rx /usr/local/bin/guess- it

Here's a test run of the script:

$ guess-it
Number-guessing Game
--------------------
I have a secret number between 1 and 100.
Enter guess #1:
50
Too low!
Enter guess #2:
75
Too low!
Enter guess #3:
83
Too low!
Enter guess #4:
92
Too high!
Enter guess #5:
87
Too high!
Enter guess #6:
85
Too low!
Enter guess #7:
86
You guessed it!
It took you 7 tries.

Another test, using an alternate upper limit:

$ guess-it 50
Number-guessing Game
--------------------
I have a secret number between 1 and 50.
Enter guess #1:
25
Too low!
Enter guess #2:
37
Too low!
Enter guess #3:
44
Too high!
Enter guess #4:
40
You guessed it!
It took you 4 tries.

4.12.1.7. Login and initialization scripts

When a user logs in, the system-wide script /etc/profile and the per-user script ~/.bash_profile are both executed. This is the default /etc/profile :

# /etc/profile
# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc
pathmunge ( ) {
 if ! echo $PATH | /bin/egrep -q '(^|:)$1($|:)' ; then
  if [ '$2' = 'after' ] ; then
   PATH=$PATH:$1
  else
   PATH=$1:$PATH
  fi
 fi
}
# ksh workaround
if [ -z '$EUID' -a -x /usr/bin/id ]; then
 EUID=Qid -uQ
 UID=Qid -ruQ
fi
# Path manipulation
if [ '$EUID' = '0' ]; then
 pathmunge /sbin
 pathmunge /usr/sbin
 pathmunge /usr/local/sbin
fi
# No core files by default
ulimit -S -c 0 > /dev/null 2>&1
