I don't want to use echo because I want the first line to be a comment, and the rest to be values that a script reads from. If the user deletes the commented line like they're not supposed to, i want the script not to fail and to replace the line. I want sed to say:
but only to the first line. I don't want #CUSTOM to be all over the place where there's new lines.
my commands go in order: touch infile; sed (add #CUSTOM to beginning of this file). I don't want each iteration of the script to add #CUSTOM to the beginning. ONLY if line one is empty or does not contain #CUSTOM

DtEditorGoToLine(library call) DtEditorGoToLine(library call)
NAME
DtEditorGoToLine -- move the insert cursor for a DtEditor widget to a specified line
SYNOPSIS
#include <Dt/Editor.h>
void DtEditorGoToLine(
Widget widget,
int lineNumber);
DESCRIPTION
The DtEditorGoToLine function moves the insert cursor for the DtEditor widget to the beginning of the line specified by the lineNumber
argument. The cursor can be moved to the last line by specifying DtEDITOR_LAST_LINE as the line number. If the line is not currently on-
screen, the contents for the DtEditor widget are scrolled to display the new insertion position.
The lineNumber argument is the number of the line in the file, counting from 1. If the lineNumber argument is less than 1, the insert cur-
sor is placed at the beginning of the first line. If the argument is greater than the total number of lines, the cursor is placed at the
last line of text.
The insert cursor can be moved to a specific character position with DtEditorSetInsertionPosition(3). The DtNtopCharacter resource can be
used to control which line is displayed at the top of the DtEditor widget.
The widget argument specifies the DtEditor widget ID.
The lineNumber argument specifies the line number within the DtEditor widget.
For a complete definition of the DtEditor widget and its associated resources, see DtEditor(3).
RETURN VALUE
The DtEditorGoToLine function returns no value.
