I have an input file that contains a name of a file followed by the pathname like so
I'm trying to write a bash script where if a path name is present, grep for a certain key phrase. I tried the following, but to no avail, it does not work.
As an added twist, I want to have the searched grep results replace the pathname ($line if it is a path). I know, it's pretty weird...
How can I get the results of a find back without the pathname
for example if i do
find ../../ -name \*.sql
i dont want to see
directory/directory/filename.sql
I only want to see filename.sql (3 Replies)

With C Shell you can get the root, head, tail and extension of a pathname by using pathname variable modifiers.
Example Script:
#! /bin/csh
set pathvar=/home/WSJ091305.txt
echo $pathvar:r
echo $pathvar:h
echo $pathvar:t
echo $pathvar:e
The result of executing this script is:

I am wondering if there's an easy way to extract individual directories from a pathname in a csh script. For example, if I have a shell variable such as
set datadirlist = /space/quimby/1
can I get 'space', 'quimby', and '1' and assign it individually to another variable?
Any suggestions... (2 Replies)

Hi!
If your working directory contains a file you want to work on, or give as an argument, you don't have to give the explicit pathname, just the filename, like so:
$ vi while_loop.ksh
But if you want execute an executable file, you must supply the explicate pathname, like so:

ppmtosixel
ppmtosixel(1) General Commands Manual ppmtosixel(1)NAME
ppmtosixel - convert a portable pixmap into DEC sixel format
SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC
LJ250 color inkjet printer.
If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table
begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS -raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com-
pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni-
tude larger than a compressed file and prints much slower.
-margin
If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci-
fied, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.
BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was
greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the
color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation.
