Ubuntu – Bash scripting problem on echo -ing the current working directory

bashcommand linescripts

I have this code:

#!/bin/bash 

#clear screen
clear 

# Ask for name of directory to create
echo "Please enter a directory name"
echo "that you wish to create"
read dir1

# create directory
mkdir $dir1

# change to the newly created directory
cd $dir1

# Tell user where he/she is
echo "This directory is called 'pwd'"


# create some files
touch file1 file2 file3


# put in some content 
echo "This is $dir1/file1" > file1
echo "This is $dir1/file2" > file2
echo "This is $dir1/file3" > file3



# announce file names
echo "The files in $dir1 are: "
ls -hl

# show the contents  of the files
echo "The content of the files are: "
cat file1
cat file2
cat file3


echo "Goodbye"

The line with echo "This directory is called 'pwd'" refuses to give the current working directory as expected. Please help me resolve this issue, I am currently learning BASH SHELL SCRIPTING

You have to use

echo "This directory is called $(pwd)"

What you are trying to do is called command substitution. This used to be done using backticks (` `), but the currently recommended way is using $().

You can find a detailed explanation in this wiki page.

Ubuntu – find: missing argument to -exec

The \ in -exec md6sum {} \; is necessary to prevent the shell from interpreting the ; character as command separator. If Java does not execute the command in a shell, try removing the escaping \\ so that the code becomes:

Runtime rt = Runtime.getRuntime();
Process pr = rt.exec("find testDir -type f -exec md5sum {} ;");

I have just confirmed this behavior with the next test program:

import java.io.*;
class Xx {
    public static void main(String args[]) throws Exception {
        Process p = Runtime.getRuntime().exec("/bin/echo \\;");
        InputStream in = p.getInputStream();
        int c;
        while ((c=in.read()) != -1)
            System.out.write((char)c);
        p.waitFor();
    }
}

Compiled with javac Xx.java, java Xx outputs \;. If I remove the \\, it'll print ; as expected.

Ubuntu – Only delete files but not folders with rm

rm won't delete directories by default. So in your example, assuming you're in the parent directory and those are all the files, all you need is:

rm *

That's a dangerous command. If you forget where you are, a command like that can wipe out important $HOME files, wipe out a load of photos, cancel Christmas, etc, etc, etc. Make sure you know what * is selecting before you run it. echo * is a good way to test the expansion.

A sane person presented with file1 file2 file3 might run rm file* or rm file{1..3} to use some of Bash's expansion code and not catch any stragglers you hadn't thought of in the crossfire.

To delete directories you need to specify either:

-d to delete empty directories, or
-r to recursively delete files and their directories.
