When i put this in my script:
Code:
seq 0 10
seq 5 10
seq 1 100

" #! /bin/bash 

count_up () 
{
  echo "Couting UP"
  n=0 
  until [[ $n -gt $1 ]]
  do
    printf "$n \n" 
    n=$(( $n + 1 )) 
  done 
}


count_down () 
{
  echo "Couting DOWN"
  n=$1
  while [[ $n -gt 0 ]]
  do
    printf "$n \n" 
    n=$(( $n - 1 )) 
  done 
} 

count_up $1
count_down $

seq 1 10 
seq 5 10 
seq 1 100 "

the output that I get when I run the script "bash lab5-4.sh 1 10" i get this:
Code:
bash lab5-4.sh 1 10
Couting UP
0 
1 
Couting DOWN
lab5-4.sh: line 19: [[: $: syntax error: operand expected (error token is "$")

seq

SEQ(1)								   User Commands							    SEQ(1)

NAME

       seq - print a sequence of numbers

SYNOPSIS

       seq [OPTION]... LAST
       seq [OPTION]... FIRST LAST
       seq [OPTION]... FIRST INCREMENT LAST

DESCRIPTION

       Print numbers from FIRST to LAST, in steps of INCREMENT.

       Mandatory arguments to long options are mandatory for short options too.

       -f, --format=FORMAT
	      use printf style floating-point FORMAT

       -s, --separator=STRING
	      use STRING to separate numbers (default: 
)

       -w, --equal-width
	      equalize width by padding with leading zeroes

       --help display this help and exit

       --version
	      output version information and exit

       If FIRST or INCREMENT is omitted, it defaults to 1.  That is, an omitted INCREMENT defaults to 1 even when LAST is smaller than FIRST.  The
       sequence of numbers ends when the sum of the current number and INCREMENT would become greater than LAST.  FIRST, INCREMENT, and  LAST  are
       interpreted  as	floating  point values.  INCREMENT is usually positive if FIRST is smaller than LAST, and INCREMENT is usually negative if
       FIRST is greater than LAST.  FORMAT must be suitable for printing one argument of type 'double'; it defaults to %.PRECf	if  FIRST,  INCRE-
       MENT, and LAST are all fixed point decimal numbers with maximum precision PREC, and to %g otherwise.
