pathmerge

help output

``` Usage: pathmerge [OPTIONS] [paths]...

Arguments: [paths]... list of paths to include

Options: -d, --delimiter Specify delimiter to use, bash ':', fish ' ' [default: :] -p, --path Path string [env: PATH=/home/user/bin:/usr/bin:/usr/local/bin:/usr/local/sbin] -s, --sort If the resulting output should be sorted -h, --help Print help -V, --version Print version ```

Example Usage

Pull PATH from env and append

```sh PATH="/path1:/path2:/path3" PATH="$(pathmerge /path4)" echo $PATH

output

/path1:/path2:/path3:/path4 ```

Provide PATH and append

```sh NEWPATH="$(pathmerge --path /a:/b:/c /z)"

echo $NEWPATH

output

/a:/b:/c:/z ```

Deduplicate occurs automatically

```sh UGLYPATH="/a:/b:/c:/a:/a:/c:/b:/c" CLEANPATH="$(pathmerge --path $UGLYPATH)

echo $CLEANPATH

output

/a:/b:/c ```

Merge/Deduplicate based on a different delimiter

```sh PATH="/a /b /c /c /c" NEWPATH="$(pathmerge --delimiter ' ' /z)"

echo $NEWPATH

output

/a /b /c /z ```

Sorting

```sh PATH="/c:/a:/b" NEWPATH="$(pathmerge --sort)"

echo $PATH

output

/a:/b:/c ```

Additional information

• Specifying the delimiter does not cause the output to change the delimiter, only what the logic triggers off of.
• pathmerge does not modify anything in the shell or environment, it only allows you to manipulate PATH formatted strings and outputs those strings. It is still up to the user to push those strings into their appropriate environment variable. e.g. PATH=$(pathmerge) to read from env, Deduplicate then push back into the PATH variable.
• pathmerge is primarily expected to be called/used by .profiles and .*rc files.
