You cannot achieve this with chmod, you can "chmod 000 inputfile.txt && chown root:root inputfile.txt", thus making file owned by root and noone can "cat" the file for example. Making "hidden" files is being done by renaming the file to ".inputfile.txt" but even then someone can do "ls -la" and he will still see the file.

I have been going through our environment and I see we have a few servers with LVM's setup and the file system type is still set to "83" within fdisk. If I change this to "8e", will it hurt the data or cause any loss? I need to know for sure before I make the change. (1 Reply)

pstopdf(1) BSD General Commands Manual pstopdf(1)
NAME
pstopdf -- convert PostScript input into a PDF document.
SYNOPSIS
pstopdf [inputfile] [-o outname] [-l] [-p]
DESCRIPTION
pstopdf is a tool to convert PostScript input data into a PDF document. The input data may come from a file or may be read from stdin. The
PDF document is always written to a file. The name of the output PDF file is derived from the name of the input file or may be explicitly
named using the -o option.
Flags:
-o outname
The name of the output file to create. If an explicit file name is not supplied, the output file will be created in the current
directory and named foo.pdf for an input file named foo.ps
-l Specifies that any messages generated during file conversion be written to a log file. For an output file named foo.pdf the generated
log file is foo.pdf.log rather than generated to stdout. If there are no messages, the log file is not generated.
-p Generates a simple progress message to stdout at the end of each page. Because conversion of complex or lengthy PostScript input can
take time, it is sometimes useful to see that progress is being made. Progress messages are always written to stdout even when the -l
(log file) option is specified.
EXAMPLES
pstopdf inputfile.ps Creates a PDF file named inputfile.pdf from the PostScript data in the input file inputfile.ps
pstopdf -o outputfilename Creates a PDF file named outputfilename from the PostScript data read from stdin.
