Why are my text files sometimes empty when I make a read to them?
My implementation:
I have a script Caller.sh that runs in the background that continuously calls the following scripts:
createtext.sh
createtext2.sh
createtext3.sh
Each of these scripts does the following (but with different text file names):
I have other scripts that read getinfo.txt, but at times, the text file is empty for up to a couple seconds...Does anybody know why? getinfo.txt should always have something in it and the mv command should work pretty fast right?
Hi,
I have this piece of shell script:
#!/bin/ksh
x=data1
x=data1
x=data1
for i in 1 2 3
do
cp x $IN_DIR
done
PerformNextTask
$IN_DIR is already designed to automatically pick up x and send x to other directory $OK_DIR. $IN_DIR will be empty once all x goes to $OK_DIR.... (2 Replies)

getinfo
GETINFO(1) General Commands Manual GETINFO(1)NAME
getinfo - get header information from a RADIANCE file
SYNOPSIS
getinfo [ -d ][ file .. ]
getinfo -
DESCRIPTION
Getinfo reads the header of each RADIANCE file and writes it to the standard output. Octree and picture files are in a binary format,
which makes it difficult to determine their content. Therefore, a few lines of text are placed at the beginning of each file by the RADI-
ANCE program that creates it. The end of the header information and the start of the data is indicated by an empty line. The -d option
can be used to print the dimensions of an octree or picture file instead. For an octree, getinfo -d prints the bounding cube (xmin ymin
zmin size). For a picture, getinfo -d prints the y and x resolution (-Y yres +X xres). If no file is given, the standard input is read.
The second form of getinfo with a hyphen simply removes the header and copies the body of the file from the standard input to the standard
output.
EXAMPLE
To print the header information from scene1.oct and scene2.hdr:
getinfo scene1.oct scene2.hdr
