copy_shell_scripts

This script will copy the *.sh files in the given directory ($PWD if not given) and its subdirectories to the destination directory.

You are prompted to overwrite existing files.

The copied files will have their permissions set to 700.

On macOS, all extended attributes of the copied files will be cleared.

The following parameter is required:

d: the destination directory; the given directory will be created if it does not exit yet

The following parameters are optional:

f: overwrite existing files without prompt
g: add group read and execute permissions; can be combined with -o
o: add other read and execute permissions; can be combined with -g

This script will error out when two or more scripts with the same name are found in the given source directory (-s).

a.sh
  /tmp/src/sub/a.sh
  /tmp/src/a.sh

In that case, you need to rename or delete one of the scripts before executing this script again.

Copy the scripts to a $PATH directory.

Example zsh setup:

$ mkdir ~/.local/scripts

~/.zshrc

export PATH="${HOME}/.local/scripts${PATH:+:${PATH}}"

Usage

$ scripts/general/copy_shell_scripts.sh -d ~/.local/scripts

$ scripts/general/copy_shell_scripts.sh -d ~/.local/scripts
$ scripts/general/copy_shell_scripts.sh -d /tmp/dst -s /tmp/src
The following script names are not unique:

a.sh
	/tmp/src/sub/a.sh
	/tmp/src/a.sh

Make the file names unique and execute this script again.
$ tree --noreport -p /tmp/src

    ├── [-rw-r--r--]  a.sh

$ rm /tmp/src/sub/a.sh                                                    (1)

$ scripts/general/copy_shell_scripts.sh -d /tmp/dst -s /tmp/src
$ tree --noreport -p /tmp/dst

├── [-rwx------]  a.sh
└── [-rwx------]  b.sh
$ scripts/general/copy_shell_scripts.sh -d /tmp/dst -s /tmp/src -g
The following files will be overwritten:

a.sh
b.sh

Do you really want to irreversibly overwrite them (Y/N)? Y
$ tree --noreport -p /tmp/dst
[drwxr-x---]  /tmp/dst
├── [-rwxr-x---]  a.sh
└── [-rwxr-x---]  b.sh

$ scripts/general/copy_shell_scripts.sh -d /tmp/dst -s /tmp/src -o -f     (2)
$ tree --noreport -p /tmp/dst
[drwx---r-x]  /tmp/dst
├── [-rwx---r-x]  a.sh
└── [-rwx---r-x]  b.sh

$ scripts/general/copy_shell_scripts.sh -d /tmp/dst -s /tmp/src -g -o -f
$ tree --noreport -p /tmp/dst
[drwxr-xr-x]  /tmp/dst
├── [-rwxr-xr-x]  a.sh
└── [-rwxr-xr-x]  b.sh

1	resolve the situation by deleting one of the scripts
2	also add `-f` so we do not get asked if we want to overwrite the files
