What does #Source: mean/do?

[toad3000]

Some example scripts I see on the top after #!/bin/bash I see #Source: ......
The .... contains just random words. I suppose they are other script names.

Thanks

Sometimes it depends on the context. Do you have an example?

[toad3000]

I have a hunch that it means run this script first and use the variables but when I tried an example of my own it didn't work. Like I made a script with variables x=100. I made another script with variable y with value 50. And in that script I said if [ $x -le $y ] ........
But when I ran the second script it says unary operator expected.

This is one of the examples I'm studying from

#!/bin/bash
#Source: countod
#read in a number of strings from user (until
#user enters  END  or end) and output the total
#number of strings that are  files  & the total
#number that are directories.
#note: if the user enters more than one string on a line,
# will get if [ -f str1 str2 etc ] bash syntax error


typeset -i  ordfile=0
typeset -i  dirfile=0


while  [ true ]
do
     echo  Enter a file name or  END to quit
     read filenam
     if  [ "$filenam" = "END" -o "$filenam" = "end" ]
     then
          break       #breaks out of the while loop, like in C
                  #continue statement also available
     fi
     if   [ -f  $filenam ]
     then
          ordfile=ordfile+1
     elif  [ -d $filenam ]
     then
          dirfile=dirfile+1
     fi
done
echo -e "The number of ordinary files:\t  $ordfile"
echo -e "The number of directories:\t  $dirfile"
exit 0

I understand the body of the script I just don't understand the #Source: part...

Thread moved to Programming Talk.

In a script such as the one you're studying, the "#" at the start of a line usually indicates a comment intended for use by a person rather than a computer.

The first line, #!/bin/bash, is a special case, sometimes known as a "shebang", which helps the command line interpreter know how to interpret the contents of a file.

I'm not familiar with "countod", it could refer to another script made by the person who produced the tutorial you are following.

This

#Source: countod
#read in a number of strings from user (until
#user enters  END  or end) and output the total
#number of strings that are  files  & the total
#number that are directories.
#note: if the user enters more than one string on a line,
# will get if [ -f str1 str2 etc ] bash syntax error

Is just the comments about the script.

The hash (#) causes the interpreter to ignore the line. In other words, it's a note for humans to read.

Without the hashes:
Source: countod
read in a number of strings from user (until user enters END or end) and output the total number of strings that are files & the total number that are directories.
note: if the user enters more than one string on a line, will get if [ -f str1 str2 etc ] bash syntax error

Could you provide the source author and title of the book or post a link to the tutorial are you studying from?
