My question please how can i eliminate 50 an 51 , i mean i'd like 25% of this list other than this two lines 50 and 51, and i'd like to specify it in the command like that
Have you an idea please ?
Thank you so much for help
Changes are in bold. I didn't test it, but it should work.
Of course if 50, 51 and friends are true line numbers counting from 1 (first line) onwards, we can simplify the new part of the script.
Beware: if you have a file of 100 lines, and you exclude 40 lines, and you want 30% of the lines, you'll get 30% of the remaining 60 lines, so you'll get 18 lines. Is this right for you, or do you still want 30 lines among the 60 remaining lines?

xdevicebell
XDEVICEBELL(3)XDEVICEBELL(3)NAME
XDeviceBell - ring a bell on a device supported through the input extension
SYNOPSIS
#include <X11/extensions/XInput.h>
Status XDeviceBell( Display *display,
XDevice *device,
XID feedbackclass,
XID feedbackid,
int percent);
display
Specifies the connection to the X server.
device
Specifies the device with which the bell is associated.
feedbackclass
Specifies the class of the feedback with which the bell
is associated.
feedbackid
Specifies the id of the feedback with which the bell is
associated.
percent
Specifies the volume in the range -100 to 100 at which
the bell should be rung.
DESCRIPTION
The XDeviceBell request causes the server to ring a bell on the
specified feedback of the specified device, if possible. The
specified volume is relative to the base volume for the bell.
If an invalid device is specified, a BadDevice error will be
returned. The feedbackclass and feedbackid parameters contain
values returned by an XGetFeedbackControl request and uniquely
identify the bell to ring. If a feedbackclass is specified that
does not support a bell, or if a nonexistent feedbackid is
specified, or a percent value is specified that is not in the
range -100 to 100, a BadValue error will be returned.
The volume at which the bell is rung when the percent argument
is nonnegative is: base - [(base * percent) / 100] + percent
The volume at which the bell rings when the percent argument is
negative is: base + [(base * percent) / 100]
To change the base volume of the bell, use
XChangeFeedbackControl.
XDeviceBell can generate a BadDevice or a BadValue error.
DIAGNOSTICS
BadDevice
An invalid device was specified. The specified device
does not exist, or has not been opened by this client
via XOpenInputDevice.
BadValue
An invalid feedbackclass, feedbackid, or percent value
was specified.
