How to check a string in the variable
hi,
I have a variable var1 as follows in the script.
var1="one two three desformat=PDF xyz"
I would like to check whether $var1 has a string "desformat=PDF" or not.
Is there any command I can use (not need to creat a file)?
Currently, I am using this:
if ( grep "desformat=PDF" $chkpdf 1>/dev/null )
then --$chkpdf is a file contains the string a parameter
Thanks.
Cheers,
Joseph

text::pdf::dict
Text::PDF::Dict(3pm) User Contributed Perl Documentation Text::PDF::Dict(3pm)
NAME
Text::PDF::Dict - PDF Dictionaries and Streams. Inherits from PDF::Objind
INSTANCE VARIABLES
There are various special instance variables which are used to look after, particularly, streams. Each begins with a space:
stream Holds the stream contents for output
streamfile
Holds the stream contents in an external file rather than in memory. This is not the same as a PDF file stream. The data is stored
in its unfiltered form.
streamloc
If both ' stream' and ' streamfile' are empty, this indicates where in the source PDF the stream starts.
METHODS
$d->outobjdeep($fh)
Outputs the contents of the dictionary to a PDF file. This is a recursive call.
It also outputs a stream if the dictionary has a stream element. If this occurs then this method will calculate the length of the stream
and insert it into the stream's dictionary.
$d->read_stream($force_memory)
Reads in a stream from a PDF file. If the stream is greater than "PDF::Dict::mincache" (defaults to 32768) bytes to be stored, then the
default action is to create a file for it somewhere and to use that file as a data cache. If $force_memory is set, this caching will not
occur and the data will all be stored in the $self->{' stream'} variable.
$d->val
Returns the dictionary, which is itself.
$d->copy($inpdf, $res, $unique, $outpdf, %opts)
Copies an object. See Text::PDF::Objind::Copy() for details
