Top Forums Shell Programming and Scripting Opening Files as command line arguments Post 302160724 by Cactus Jack on Tuesday 22nd of January 2008 03:41:02 PM

Hi guys still no joy on this issue. It appears that anything with an integer test condition does not work. E.g.

if [ $# - gt 1 ]
then echo "Single filename argument expected"
exit 1
fi

String tests (-z -n etc) are working fine.

However I don't know how else to exit my script if more than one argument is entered at the command line prompt.

This is the error I get when I enter a multiple argument (e.g. "wqe t") in the command line prompt:

file: line 10: [: too many arguments - this points to if [ $# - gt 1 ]
file: line 15: test: wqe: binary operator expected this points to 'if test -z $file'
file: line 21: [: wqe: binary operator expected this points to 'if test -z $file'
cat: wqe: No such file or
cat: t: No such file or directory

Any suggestions on this will be most helpful.

NAME
line - read one line from user input SYNOPSIS
timeout] DESCRIPTION
copies one line (up to a new-line) from the standard input and writes it on the standard output. It returns an exit code of 1 on EOF and always prints at least a new-line. It is often used within shell files to read from the user's terminal. Options recognizes the following command-line option: Timeout after timeout seconds where timeout is an integer value (if a non-integer value is specified, it is converted to an integer; i.e., rounded down). A blank is required between and the timeout argument. This option is not documented in POSIX and other industry standards, and should not be used in portable applications. EXTERNAL INFLUENCES
International Code Set Support Single- and multi-byte character code sets are supported. EXAMPLES
The following lines in a shell script prompt for a file name and display information about the file: To limit the response time to 10 seconds, use the form: then test for no response. If no response occurs before timeout expires, a default behavior should be provided. WARNINGS
This command is likely to be withdrawn from X/Open standards. Applications using this command might not be portable to other vendors' sys- tems. As an alternative is recommended. SEE ALSO
