How to fix :[too many arguments error in code
I am getting a :[ too many arguments error on line 28 if I do not specify a directory or file when running my code. Any suggestions as I am stuck here.
if [ $# -gt 1 ]; then
echo "Enter zero or one file"
echo "You must use a valid directory"
echo "Current directory is:" pwd
exit 0
fi
#Flag Variable
flag=1
#Code for no arguments
if [ $# -eq 0 ]; then
for filename in *
do
if [ -f $filename ]; then
linetest1='wc -l < $filename'
# Execution
if [ $flag -eq 1 ]; then
startline=$linetest1
startfile=$filename
flag=2
fi
#End Code Execution
if [ $startline -lt $linetest1 ]; then
startline=$linetest1
startfile=$filename
fi
fi
done
echo "File $startfile has the maximum number lines ($startline)."
exit 0
fi
#If only one Variable
if [ $# -eq 1 ]; then
cd $1
for filename in *
do
if [ -f $filename ]; then
linetest1='wc -l < $filename'
if [ $flag -eq 1 ]; then
startline=$linetest1
startfile=$filename
flag=2
fi
if [ $startline -lt $linetest1 ]; then
startline=$linetest1
startfile=$filename
fi
fi
done
echo "File $startfile has the maximum number lines ($startline)."
exit 0
fi
Thanks.

LEARN ABOUT PHP
id3_get_version
ID3_GET_VERSION(3) 1 ID3_GET_VERSION(3)
id3_get_version - Get version of an ID3 tag
SYNOPSIS
int id3_get_version (string $filename)
DESCRIPTION
id3_get_version(3) retrieves the version(s) of the ID3 tag(s) in the MP3 file.
If a file contains an ID3 v1.1 tag, it always contains a 1.0 tag, as version 1.1 is just an extension of 1.0.
PARAMETERS
o $filename
- The path to the MP3 file Instead of a filename you may also pass a valid stream resource
RETURN VALUES
Returns the version number of the ID3 tag of the file. As a tag can contain ID3 v1.x and v2.x tags, the return value of this function
should be bitwise compared with the predefined constants ID3_V1_0, ID3_V1_1 and ID3_V2.
EXAMPLES
Example #1
id3_get_version(3) example
<?php
$version = id3_get_version( "path/to/example.mp3" );
if ($version & ID3_V1_0) {
echo "Contains a 1.x tag
";
}
if ($version & ID3_V1_1) {
echo "Contains a 1.1 tag
";
}
if ($version & ID3_V2) {
echo "Contains a 2.x tag
";
}
?>
The above example will output something similar to:
Contains a 1.x tag
Contains a 1.1 tag
