A PDF creator and virtual PDF printer for Microsoft Windows PDF-XChange: Proprietary: Yes: PDF Tools allows creation of PDFs from many types of source input (images, scans, etc.). The PDF-XChange print driver allows printing directly to a PDF. A "lite" version of the print driver is free for non-commercial (home and academic) use. PrimoPDF ...
In computing, redirection is a form of interprocess communication, and is a function common to most command-line interpreters, including the various Unix shells that can redirect standard streams to user-specified locations. The concept of redirection is quite old, dating back to the earliest operating systems (OS).
Example usage of tee: The output of ls -l is redirected to tee which copies them to the file file.txt and to the pager less. The name tee comes from this scheme - it looks like the capital letter T The tee command is normally used to split the output of a program so that it can be both displayed and saved in a file.
The CSRG incorporated the r-commands into their Unix operating system, the Berkeley Software Distribution (BSD). The r-commands premiered in BSD v4.1. [2] Among the programs in the suite are: rcp (remote copy), rexec (remote execution), rlogin (remote login), rsh (remote shell), rstat, ruptime, and rwho (remote who). [2] [3]
Process substitution can also be used to capture output that would normally go to a file, and redirect it to the input of a process. The Bash syntax for writing to a process is >(command). Here is an example using the tee, wc and gzip commands that counts the lines in a file with wc -l and compresses it with gzip in one pass:
Unix shells use dup2 for input/output redirection. Along with pipe(), it is a tool on which Unix pipes rely. The following example uses pipe() and dup() in order to connect two separate processes (program1 and program2) using Unix pipes:
Xpdf runs on nearly any Unix-like operating system.Binaries are also available for Windows.Xpdf can decode LZW and read encrypted PDFs. The official version obeys the DRM restrictions of PDF files, [7] which can prevent copying, printing, or converting some PDF files. [4]
Under most Unixes and Unix-like operating systems, a special command is also available, typically called "buffer", that implements a pipe buffer of potentially much larger and configurable size. This command can be useful if the destination process is significantly slower than the source process, but it is desired that the source process ...
