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)

mvdelch

delch(3XCURSES) 					  X/Open Curses Library Functions					   delch(3XCURSES)

NAME

       delch, mvdelch, mvwdelch, wdelch - remove a character

SYNOPSIS

       cc [ flag... ] file... -I /usr/xpg4/include  -L	/usr/xpg4/lib 
	-R  /usr/xpg4/lib  -lcurses  [ library... ]

       c89 [ flag... ] file... -lcurses [ library... ]

       #include <curses.h>

       int delch(void);

       int mvdelch(int y, int x);

       int mvwdelch(WINDOW *win, int y, int x);

       int wdelch(WINDOW *win);

DESCRIPTION

       The  delch()  and wdelch() functions delete the character at  the current cursor position from stdscr and win, respectively.  All remaining
       characters after cursor through to the end of the line are shifted one character towards the start of the line. The last character  on  the
       line becomes a space; characters on other lines are  not affected.

       The  mvdelch()  and mvwdelch() functions delete the character at  the position specified by the x and y parameters; the former  deletes the
       character from stdscr; the latter from win.

PARAMETERS

       y      Is the y (row) coordinate of the position of the character  to be removed.

       x      Is the x (column) coordinate of the position of the character  to be removed.

       win    Is a pointer to the window containing the character to be removed.

RETURN VALUES

       On success, these functions return OK. Otherwise, they return ERR.

ERRORS

       None.
