Adding a columnfrom a specifit line number to a specific line number
Hi,
I have a huge file & I want to add a specific text in column. But I want to add this text from a specific line number to a specific line number & another text in to another range of line numbers.
To be more specific: lets say my file has 1000 lines & 4 Columns. I want to add text "Hello" to 5th column but from line 1 to line 200. & I want to add another text "goodbye" to 5th column of the same file from line 201 to 800 & another text "live" again to 5th column to the same file from line 801 to 1000.
I know I can use sed to add a column to my file but I don't know how to tell sed to add this column to from line & to to line.
this will add my desired string to the 4th column in the right place but I don't know how to limit this to a specific range of lines.
May be there is a way to do it in sed or may be awk?
Hello, I need help in appending the line number of each line to the file and also to get the total number of lines. Can somebody please help me.
I have a file say:
abc
def
ccc
ddd
ffff
The output should be:
Instance1=abc
Instance2=def
Instance3=ccc
Instance4=ddd
Instance5=ffff

ppmlabel
ppmlabel(1) General Commands Manual ppmlabel(1)NAME
ppmlabel - add text to a portable pixmap
SYNOPSIS
ppmlabel [-angle angle] [-background transparent | colour] [-colour colour] [-file filename] [-size textsize] [-text 'text string'] [-x
column] [-y row] ... [ppmfile]
DESCRIPTION
ppmlabel uses the text drawing facilities of ppmdraw to add text to a portable pixmap. The location, size, baseline angle, colour of the
text and background colour (if any) are controlled by command line arguments. The text can be specified on the command line or read from
files. Any number of separate text strings can be added by one invocation of ppmlabel, limited only by the maximum length of the command
line.
If no ppmfile is specified, ppmdraw reads its input pixmap from standard input.
OPTIONS
The arguments on the ppmlabel command line are not options in the strict sense; they are commands which control the placement and appear-
ance of the text being added to the input pixmap. They are executed left to right, and any number of arguments may appear.
All flags can be abbreviated to their shortest unique prefix.
-angle angle
Sets the angle of the baseline of subsequent text. angle is specified as an integral number of degrees, measured counterclock-
wise from the row axis of the pixmap.
-background transparent | colour
If the argument is ``transparent'', text is drawn over the existing pixels in the pixmap. If a colour is given (see the -colour
switch below for information on how to specify colours), rectangles enclosing subsequent text are filled with that colour.
-colour colour
Sets the colour for subsequent text. The colour can be specified in five ways:
o A name, assuming that a pointer to an X11-style colour names file was compiled in.
o An X11-style hexadecimal specifier: rgb:r/g/b, where r g and b are each 1- to 4-digit hexadecimal numbers.
o An X11-style decimal specifier: rgbi:r/g/b, where r g and b are floating point numbers between 0 and 1.
o For backwards compatibility, an old-X11-style hexadecimal number: #rgb, #rrggbb, #rrrgggbbb, or #rrrrggggbbbb.
o For backwards compatibility, a triplet of numbers separated by commas: r,g,b, where r g and b are floating point numbers
between 0 and 1. (This style was added before MIT came up with the similar rgbi style.)
-file filename
Reads text from the file filename and draws it on successive lines.
-size textsize
Sets the height of the tallest characters above the baseline to textsize pixels.
-text 'text string'
Draws the given text string (which must be quoted if it contains spaces). The location for subsequent text is advanced by 1.75
times the current textsize, which allows drawing multiple lines of text in a reasonable manner without specifying the position of
each line.
-x column Sets the column at which subsequent text will be left justified. Depending on the shape of the first character, the actual text
may begin a few pixels to the right of this point.
-y row Sets the row which will form the baseline of subsequent text. Characters with descenders, such as ``y'', will extend below this
line.
BUGS
Text strings are restricted to 7 bit ASCII. The text font used by ppmdraw doesn't include definitions for 8 bit ISO 8859/1 characters.
When drawing multiple lines of text with a non-transparent background, it should probably fill the space between the lines with the back-
ground colour. This is tricky to get right when the text is rotated to a non-orthogonal angle.
