Input redirection can be useful, for example, if you have written a FORTRAN program which expects input from the terminal but you want it to read from a file. In the following example,myprog, which was written to read standard input and write standard output, is redirected to readmyinand ...
In DOS, as in UNIX, the symbols for redirection are < and >. Remember the first C program, HELLO.C? It used the printf() library function to display the message Hello, world on-screen. As we now know, printf() sends output to stdout, so it can be redirected. When we enter the ...
One of the most important andinteresting topics under Linux administrationis I/O redirection. This feature of the command line enables you to redirect the input and/or output of commands from and/or to files, or join multiple commands together using pipes to form what is known as a “command...
In fact, this record is treated as part of the previous record; the newline separating them in the output is the original newline in the datafile, not the one added by awk when it printed the record! Another way to change the record separator is on the command line, using the variable...
This chapter describes the general concepts of FORTRAN input and output, and provides details on the different kinds of I/O. See also the Input/Output chapter in theFortran Programming Guide Essential FORTRAN I/O Concepts Any operating system based on the UNIX operating system is not as record...
Learn the basics of standard input, standard output, and standard error In prior Java 101 articles, I referred to the concepts of redirection, standard input device, and standard output device. To demonstrate inputting data, several examples called System.in.read(). It turns out that System...
Standard output Every Unix-based operating system has a concept of “a default place for output to go”. Since that phrase is a mouthful, everyone calls it “standard output”, or “stdout”, pronouncedstandard out. Your shell (probably bash or zsh) is constantly watching that default output...

See thecsh,ksh,andshman pages for details on redirection and piping on the command line. f77: VAX / VMS Logical File Names If you are porting from VMS FORTRAN to FORTRAN 77, the VMS-style logical file names in theINCLUDEstatement are mapped to UNIX path names. The environment variableLOGI...
The terminal connection for./a.outremains active throughstderr. To handle redirection and output tonohup.out,nohupis responsible. Ifstdoutorstderrwere to output to the terminal, it could potentially disrupt other commands sharing the terminal. This information is fromman nohup. ...
