Linux command to move all the files from var/A to var/ - linux

Question

I guess that this question has been asked here, but I didn't find it.
I am at directory var/ and I have a folder var/A that have some files inside, what I want is to move this files inside A to var/. so what i want to do is the following:
from:
var
├── A
| ├── file1.txt
| └── file2.txt
└── file3.txt
to:
var
├── file1.txt
├── file2.txt
└── file3.txt
In /var I have tryed the following commands
sudo mv A /
sudo mv A/ ./
sudo mv A/ .
And no one had worked. Thank you in advance

Answer 1

I have found the answer:
mv A/* .
I hope it could help another one

You have to specify the right path or match
if you want to move the entire files or directory you have to something
like this using * (wildcards)
user#akuma:~/var$ mv ./A/* ./
You can type mv --help in your terminal for more information to see more option like below
user#akuma:~/WORKSPACE/Trash$ mv --help
Usage: mv [OPTION]... [-T] SOURCE DEST
or: mv [OPTION]... SOURCE... DIRECTORY
or: mv [OPTION]... -t DIRECTORY SOURCE...
Rename SOURCE to DEST, or move SOURCE(s) to DIRECTORY.
Mandatory arguments to long options are mandatory for short options too.
--backup[=CONTROL] make a backup of each existing destination file
-b like --backup but does not accept an argument
-f, --force do not prompt before overwriting
-i, --interactive prompt before overwrite
-n, --no-clobber do not overwrite an existing file
If you specify more than one of -i, -f, -n, only the final one takes effect.
--strip-trailing-slashes remove any trailing slashes from each SOURCE
argument
-S, --suffix=SUFFIX override the usual backup suffix
-t, --target-directory=DIRECTORY move all SOURCE arguments into DIRECTORY
-T, --no-target-directory treat DEST as a normal file
-u, --update move only when the SOURCE file is newer
than the destination file or when the
destination file is missing
-v, --verbose explain what is being done
-Z, --context set SELinux security context of destination
file to default type
--help display this help and exit
--version output version information and exit
The backup suffix is '~', unless set with --suffix or SIMPLE_BACKUP_SUFFIX.
The version control method may be selected via the --backup option or through
the VERSION_CONTROL environment variable. Here are the values:
none, off never make backups (even if --backup is given)
numbered, t make numbered backups
existing, nil numbered if numbered backups exist, simple otherwise
simple, never always make simple backups

I managed to replicate your situation.
.
└── var
├── A
│   ├── file1.txt
│   └── file2.txt
└── file3.txt
2 directories, 3 files
user#host:~/soQ$ mv var/A/*.txt var/ && rm -rf var/A/
user#host:~/soQ$ tree
.
└── var
├── file1.txt
├── file2.txt
└── file3.txt
Hope this helps!
If you want to do this from var just do mv A/*.txt . && rm -rf A/
Also, let's assume you have the following structure in your directory.
.
├── A
│   ├── file3.txt
│   └── folder1
│   ├── file1.txt
│   └── file2.txt
└── file4.txt
If you want to copy just the *.txt file in var you need to use find like this:
find ./A/* -type f -exec mv {} ${PWD} \; && rm A
This looks at all the files and folders and returns the path for each file (each .txt for example) and then executes mv on each line and moves the files into the current directory (${PWD}).
