Top Forums Shell Programming and Scripting insert predefine text in front and on a loop Post 302496116 by Scott on Saturday 12th of February 2011 10:13:01 AM

In a loop:
Code:
CHR=(a b c d)
while read LINE; do
  [ -z "$LINE" ] && p=0 && echo && continue
  echo ${CHR[((${p:-0}%4))]}=$LINE
  ((p=p+1))
done < file1

What's always expanding? The input data or the "predefined" text?

If the latter:
Code:
awk -v c=97 '
  /^$/ { c=97; print; next }
  { printf "%c %s\n", c++, $0 }
' file1

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. SEE ALSO
