Top Forums UNIX for Beginners Questions & Answers Delete a "G" character from df -h result Post 303033055 by RudiC on Friday 29th of March 2019 08:06:35 AM

Welcome to the forum.


Please stick to the rules (e.g. use code tags), and be careful and consistent when presentig your problem (e.g. df -h in the title while df -BG in the post).


For your problem, none of the two, be it df -h or df -BG, is the option of choice, as the results displayed may suffer from improper rounding effects, and you always ask yourself are those units for 2^30 or 1E9 multipliers. Use blocks or bytes instead, and calculate to taste.


To remove the G character, use awk's sub() function for every field that it applies to, e.g. sub (/G/, "", $3).
If using df -B1, try int($3/2^30+.5)

amc-note

AMC-NOTE(1)						       Auto Multiple Choice						       AMC-NOTE(1)

NAME

       AMC-note - computes marks after scans data capture for AMC multiple choice exams.

SYNOPSIS

       auto-multiple-choice note --data project-data-dir [--seuil threshold] [--grain granularity] [--arrondi rounding] [--notemin min]
			    [--notemax max] [--no-plafond | --plafond]

DESCRIPTION

       The AMC-note.pl command computes marks for all students from the scoring strategy extracted from the LaTeX source file by AMC-prepare(1)
       and from the data capture reports made by AMC-analyse(1).

       --data project-data-dir
	   gives the directory where data files are (see for example AMC-meptex(1)).

       --seuil threshold
	   gives the black ratio threshold (see AMC-analyse(1)) for deciding whether a box is ticked or not.

       --grain granularity --arrondi rounding
	   ask marks to be rounded to a multiple of granularity. If rounding is 'i', rounding is done from below (as with floor(3)). If rounding
	   is 'n', rounding is done to the nearest multiple of granularity. If rounding is 's', rounding is done from above (as with ceil(3)). For
	   example, with options "--grain 0.25 --arrondi s", mark 6.285 is rounded to 6.5.

       --notemin min
	   with this option, all marks below min will be replaced by min.

       --notemax max
	   gives the mark to associate to a sheet where all answers are correct. If not used, marks are not scaled.

       --plafond
	   with this option, all marks above max will be replaced by max.

       --debug file.log
	   gives a file to fill with debugging information.

       --postcorrect-student s --postcorrect-copy c
	   requests port-correction from the completed answer sheet identified by student and copy numbers. In post-correction mode, correct
	   answers are not extracted from the LaTeX source file, but taken from the answers given on this sheet.
