Reading from a File and Using as an Input variable
I need to know how the the string constant from Input File should be read and provide as input data for the script .
I would like to read some constant values from the file and feed that as an input to the script, something like this.
From above syntax, Im just using the Constant String from the input text, but script should perform actions on all the instances of variable string mapped to the constant from input text. Can some one provide me the method how to call this . Do i need to write any functions for this?
I would like to prompt for input and then use it as a variable in a script.
Something like this.
#!/bin/ksh
echo "What is your name?: \c"
read response
echo "Your name is $reply" >file.txt
done
exit 0
What am I missing?
Thanks, (7 Replies)

I am trying to read input for a C program (that expects input from the user) from a file using the shell command:

Arch::TempFiles(3pm) User Contributed Perl Documentation Arch::TempFiles(3pm)NAME
Arch::TempFiles - help to manage temporary files/dirs
SYNOPSIS
use Arch::TempFiles qw(temp_file_name temp_file temp_dir);
# all will be removed automatically on the script completion
my $file_name1 = temp_file();
my $file_name2 = temp_file_name("status");
my $dir_name = temp_dir("arch-tree");
use Arch::TempFiles;
my $tmp = new Arch::TempFiles;
$tmp->root($tmp->dir);
my $file_name = $tmp->name;
open OUT, ">$file_name";
close OUT;
DESCRIPTION
This module deals with temporary file names. It is similar to File::Temp, but simplier and more focused. Also, File::Temp is relatively new
and was not shipped with older perl versions.
Both function interface and object oriented interface are supported.
FUNCTIONS /METHODS
The following functions are available:
temp_root, temp_name, temp_file_name, temp_dir_name, temp_file, temp_dir.
The corresponding class methods are available too:
root, name, file_name, dir_name, file, dir.
temp_root [dir]
$tmp->root [dir]
Change or return the root of the temporary files and dirs. The default is either $ENV{TMP_DIR} or "/tmp".
temp_name [label]
$tmp->name [label]
Return the unused temporary file name. The default file name is "/tmp/,,arch-XXXXXX" where XXXXXX is a random number. To change this
name use "temp_root" and/or provide label that replaces "arch".
Please note, that the operation of acquiring the file name using this function/method and actual creating of this file is not atomic.
So you may need to call this method again if the creation is failed, for example if some other process created the same file in the
middle.
temp_file_name [label]
$tmp->file_name [label]
Like "temp_name", but stores the name in the file list that will be removed on the end (on object destruction).
temp_dir_name [label]
$tmp->dir_name [label]
Like "temp_name", but stores the name in the dir list that will be removed on the end (on object destruction).
temp_file [label]
$tmp->file [label]
Like "temp_file_name", but also creates the file.
temp_dir [label]
$tmp->dir [label]
Like "temp_dir_name", but also creates the dir.
BUGS
Awaiting for your reports.
