I need to do a substitution: CPF to ,C,P,F, CPM to ,C,P,M, SPF to ,S,P,F etc. I can do each of them with separate substitutions e.g. s/CPF/,C,P,F/ but I'd like to know if there is a more elegant solution. In general, how can I use the results of the search in the substitution, ... (3 Replies)

Hi,
Is there a way to simplify the below script? Because I am having problems executing this if I added this to CRON. Also, you may notice that its objective is to put all information in one file (rm1.txt). And in addition file "sRMR_6.txt" to sRMR_23.txt" changes its information everyday.... (4 Replies)
Hello,
I have a large number of sed commands that I execute one after the other, simply because I don't know if there's a shorter way to do it. I hope someone can help me save some time :-)
These are my commands:

Hi all, I don't have much experience with shell scripting and I was wondering if there's a shorter way to write this.

PLSCMAP1L(3plplot) PLplot API PLSCMAP1L(3plplot)NAME
plscmap1l - Set color map1 colors using a piece-wise linear relationship
SYNOPSIS
plscmap1l(itype, npts, pos, coord1, coord2, coord3, rev)
DESCRIPTION
Set color map1 colors using a piece-wise linear relationship between position in the color map (from 0 to 1) and position in HLS or RGB
color space (see the PLplot documentation). May be called at any time.
The idea here is to specify a number of control points that define the mapping between palette 1 input positions (intensities) and HLS (or
RGB). Between these points, linear interpolation is used which gives a smooth variation of color with input position. Any number of con-
trol points may be specified, located at arbitrary positions, although typically 2 - 4 are enough. Another way of stating this is that we
are traversing a given number of lines through HLS (or RGB) space as we move through color map1 entries. The control points at the minimum
and maximum position (0 and 1) must always be specified. By adding more control points you can get more variation. One good technique for
plotting functions that vary about some expected average is to use an additional 2 control points in the center (position ~= 0.5) that are
the same lightness as the background (typically white for paper output, black for crt), and same hue as the boundary control points. This
allows the highs and lows to be very easily distinguished.
Each control point must specify the position in color map1 as well as three coordinates in HLS or RGB space. The first point must corre-
spond to position = 0, and the last to position = 1.
The hue is interpolated around the "front" of the color wheel (red<->green<->blue<->red) unless the "rev" flag is set to true, in which
case interpolation (between the i and i + 1 control point for rev[i]) proceeds around the back (reverse) side. Specifying rev=NULL is
equivalent to setting rev[]= false for every control point.

ARGUMENTS
itype (PLBOOL, input)
true: RGB, false: HLS.
npts (PLINT, input)
number of control points
pos (PLFLT *, input)
position for each control point (between 0.0 and 1.0, in ascending order)
coord1 (PLFLT *, input)
first coordinate (H or R) for each control point
coord2 (PLFLT *, input)
second coordinate (L or G) for each control point
coord3 (PLFLT *, input)
third coordinate (S or B) for each control point
rev (PLBOOL: *, input)
reverse flag for each control point. (rev[i] refers to the interpolation interval between the i and i + 1 control points).
