Question

Hello! In this bash program, there is an error when i try to execute it.

I am running it on Unix and I used emacs for the text editor

it says:

line 3: [0: command not found

line 9: if[-f ]: command not found

line 10: syntax error near unexpected token `then'

line 10: `then'

-------------------------------

#!/bin/bash

if [ $# != 1 ]
then
echo "Usage: myScript.sh "
exit 1
fi

if [ -f $1 ]
then

awk '
BEGIN {
i=0
flag=0
avg=0
total=0
}
{
tmp =0
count=0
sum=0
flag = 0
for(i=1; i<=2; i++)
{
printf("%s ", $i);
}

for(i=3; i<=NF; i++)
{
tmp = $i + 0
if ($i == 0)
{
flag =1
}
printf("%s ",$i);
if(tmp || flag)
{
sum = sum + tmp
count++
}
}
printf("%d %d", sum, (sum/count) +0.5);

printf("\n");
}

END {

}
' < $1

else

echo "Error: file $1 does not exist"
fi

Answer 1

Please find the right script and following errors could be introduced by you.

1. You have leave space between "if" and "[" not as "if[ $# != 1]". So it should be like this"if [ $# != 1 ]"

2. And the same is in "if[ -f". So it should be like this "if [ -f $1 ]"

3. Use emacs to type the same program with exact spaces as mentioned above and right syntax

Program Screen Shot:

if[$# != 1 ] then echo "Usage: myscript.ah" exit 1 fi if -$1 then awk' BEGIN flag avg o total-0 tmp =0 count-0 sum-0 flag 0 for (i-1 ; i<-2 ; i++) print f ("%s ", $i); flag 1 print f ("55 ",Si); if (tmp l flag) umsum tmp count++ printf ("%d %d", (sum/count) +0.5); sum, printf("n") END $1 echo "Error: file $1 does not exiat" Ei
