You must open file in r (read) mode or atleast mode that. Although the steps may differ depending on the distribution that you’re using, you can usually find the command line in the Utilities section. If you are still unsure about the command-line interface, check out this CLI tutorial. Open a file using fopen () function and store its reference in a FILE pointer say fPtr. Before we go on to the list of commands, you need to open the command line first. Step by step descriptive logic to read a file and display file contents.

fread () - Read block of raw bytes from file.

In case if require to install python click here. fscanf () - Use this to read formatted input from file. Note: Latest all linux dist comes with both Python 2.7 and Python 3.5 by default. The difference between python and python3 occur when divided(fractional) operation occur, to avoid the issue see below python vs python3. If python is installed, you can do a lot of mathematical operation through command line. That said, extracting the data for given partition number(s) and dealing with "M", "G" suffixes, as the original question seemed to ask for, might call for (g)awk rather than bc. Another fact that suggests to prefer the build-in arithmetic capabilities for such simple calculations, rather than an external program.

It also has a lot of other helpful tools, such as min/maximising windows and move the position of a window (which is something you could.

You could also get CMDOW, a Command Line Utility which allows you to resize the window of command prompt (or any window, for that matter) to the pixel. |bc`).Ĭoncerning verbosity, the bc command allows the option -q which suppresses output of the "normal GNU bc welcome".Īs a final, slightly borderline remark, let's note that bc is not just a calculator but rather a full-fledged programming language (including user defined functions, while & for loops, etc etc). Re: Set Size of Command Prompt Window - Batch File. However, to use the result in a script, this will most probably be shorter than the bc solution (which could be, e.g., `echo.

To see the result, you'd indeed have to type echo $((.)), which makes some characters more than (interactive use of) bc. I could not double-check whether this is part of the POSIX standard, but I did check that it also works on Cygwin and the Mingw32 shell. There are several solutions listed (shell, awk, dc, perl, python, etc.).Ī function may be defined with any option (gawk seems to be the most flexible to use) c () ' < /dev/nullĪnd use: $ c 22* 33 /7 # spaces or not, it doesn't matter.ġ03.714285714285714285714285714285714285714285714285714285714Īs remarked in a comment to an earlier reply, the standard shell (ba)sh allows to evaluate arithmetic expressions within $((.)).
