Copy particular file using "ls -ltr"
Hi all,
I am new in shell scripting and trying to write a script which does the following:
Code:
#!/bin/bash
$PATH =/a/b/c
ls -ltr $PATH
$VARIABLE=???

Code:
$ls -ltr $PATH
-rw-r--r-- 1 18401 1399  127474 Apr 13 07:21 file_abc_1.txt
-rw-r--r-- 1 18401 1399  127474 July 13 07:21 file_abc_2.txt
-rw-r--r-- 1 18401 1399  127474 Aug 13 07:21 file_abc_3.txt
-rw-r--r-- 1 18401 1399  127474 Aug 13 07:21 file_cdf_1.txt

I would like the script to copy the filename (for example: file_abc_3.txt). The latest $PATH/file with txt file_abc* and assign it to some VARIABLE which I want to use further in the script.

Also I would like to ask if I can assign another variable (varB=/a/b/c/file1/txt) from a txt file (text below)
Code:
version: version 2.1
Working directory:  /a/b/c
Data: /source/path/
Total files: 212
Calculated summary file: /a/b/c/file1/txt
log file: /a/b/log.txt

Thanks in advance,
emily

I do not understand the second question. What are you trying to get?

First question, one way to do what you want
Code:
var=$( ls -rt | tail -1 )

$var now contains the filename

Thanks for the first question.

In the second question I want to have another variable assignment. From the txt file, I want the variable2 to have the value /a/b/c/file1/txt

Is it clear now?

thanks
