I am using the below code to chose a file to view :
Everything works fine as long as I am giving the correct choice .
But when i give a wrong option it hangs .
How to include a check so that if a wrong option is entered , throw a message saying to enter a valid choice.
I have a file containing a list of references and I want to run a script that will make the same action for each reference.
The input file changes every hour, it's why I want to use a script that can read in a file, record by record, and run a specific action for the reference readed.
Thanks... (1 Reply)
Hey,
examples of the input (text line):
/bla/blMOasdn234.adanif24/blabla.rar
/bla/blMOasdn234.adanif24/blabla23124.bin
/bla/bla/bla/bla/bla/bla.bin
and what I need to do is extract/select only the dir path so the output would be:
/bla/blMOasdn234.adanif24/
/bla/blMOasdn234.adanif24/... (4 Replies)
Hi all,
I have a problem with qwk command.
i have to check process status and for that i am using command
prstat -mvL 1 1
and it gives me the entire output
but when i use this command with awk like this:
prstat -mvL 1 1 | awk -F" " '{print $1,$15}'
to get first and 15th arguments.

Okay -- I hope I ask this correctly.
I'm working on my little shell script to write vendor names and aliases to files from user input. If a user choose to add to a file, he can do that as well. I'm using a select loop for this function to list all the possible files the user can choose from.... (7 Replies)
Hi all,
Before I give up on using SELECT for my first attempt at creating a menu driven script, can anyone please advise if it is possible to include a line break for PS3, I've tried putting in a \n and it does not work.
Tried for both bash and ksh and both gives the same result. Preference... (3 Replies)

I have a select menu driven script using a case statment and cannot control what happens after a user's input is just <ENTER> or the <SPACEBAR>+<ENTER>. I want it to just hit the "MAIN" function and not redraw the options. I've look everywhere for the answer and am at a loss.
Here's the code:... (4 Replies)

A lot of my scripting makes use of the 'select' command to create menu driven input. A typical example of how I use it is as:

dchist
DCHIST(1) DICOM PS3 - DICOM image statistics DCHIST(1)NAME
dchist - ACR/NEMA DICOM PS3 ... DICOM PS3 - DICOM image statistics
SYNOPSIS
dchist [ -h|histogram ] [ -csv ] [ -withhighbits|highbitsonly ] [ -v|verbose ] [ -filename ]
DESCRIPTION
dchist reads the named dicom or acr-nema input file and describes the statistics of the image pixel data. The primary intent is to deter-
mine the zero order entropy of the image.
The description and verbose output go to standard error.
The basic input switches are described in dcintro(1). Options specific to this program are:
-h|histogram
Display table of pixel value, frequency, probability, contribution to zero order entropy, and cumulative zero order entropy. May
generate a LOT of output !
-csv
Display only a comma separated value pair of pixel value and frequency, one line per value, e.g., for import into a statistical pro-
gram or spreadsheet
-withhighbits
Include as well the values that are above Bits Stored and within Bits Allocated, such as might be overlay bits (regardless of
whether or not there are any 60xx group elements).
-highbitsonly
Use instead the values that are above Bits Stored and within Bits Allocated, such as might be overlay bits, and treat all valid
pixel values below Bits Stored inclusive as zero (regardless of whether or not there are any 60xx group elements).
-v|verbose
Display byte offset from file start and message start, in hexadecimal, and dump contents while reading and once read.
-filename
Show the name of the file supplied in the arguments; a hyphen will be reported if no filename was supplied.
ENVIRONMENT EXAMPLES
% dchist expmeta.dc3
9.02366 Zero order entropy (bits per pixel)
0x0 Smallest symbol value
0 Smallest symbol length (bits)
0x6e9 Largest symbol value
11 Largest symbol length (bits)
% dchist -h expmeta.dc3
[0x0] 392 p=0.00598145 e=0.0441747 cum=0.0441747
...
[0x6e9] 1 p=1.52588e-05 e=0.000244141 cum=9.02366
9.02366 Zero order entropy (bits per pixel)
0x0 Smallest symbol value
0 Smallest symbol length (bits)
0x6e9 Largest symbol value
11 Largest symbol length (bits)
