I have a directory name stored in a variable. Does anyone have a piece of code which checks if this stored directory name ends up with the "/" and if it is missing adds it to the same variable. for example I might have
A=/bb/data or A=/bb/data/
which needs to be A=/bb/data/ for sure
thanks... (5 Replies)
Hi
I have a variable which holds full path to the file, for example
z=/bb/data3/f4222pdb.dta.new
I need to remove the extension .new so it would look like
z=/bb/data3/f4222pdb.dta
Is there a command to do this? This variable is used in the "for" loop later. I am in ksh. Thanks a lot -A (4 Replies)

ppmtopgm
ppmtopgm(1) General Commands Manual ppmtopgm(1)NAME
ppmtopgm - convert a portable pixmap into a portable graymap
SYNOPSIS
ppmtopgm [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces a portable graymap as output. The output is a "black and white" rendering of the original
image, as in a black and white photograph. The quantization formula used is .299 r + .587 g + .114 b.
Note that although there is a pgmtoppm program, it is not necessary for simple conversions from pgm to ppm , because any ppm program can
read pgm (and pbm ) files automatically. pgmtoppm is for colorizing a pgm file. Also, see ppmtorgb3 for a different way of converting
color to gray. And ppmdist generates a grayscale image from a color image, but in a way that makes it easy to differentiate the original
colors, not necessarily a way that looks like a black and white photograph.
QUOTE
Cold-hearted orb that rules the night
Removes the colors from our sight
Red is gray, and yellow white
But we decide which is right
And which is a quantization error.
