Stubs of wget and curl for aria2c to download large files using Debian alternatives subsystem instead of changing the shell scripts. aria2c is better when compareed to wget/curl because it tries to utilize your maximum download bandwidth. Since, changing shell scripts from wget/curl to equivalent aria2c cli takes time, this stub translates the wget/curl command to equivalent aria2c command and executes it. If not possible to do so, it executes the original command.
- Install aria2c
- Install wget and(or) curl
- Copy original wget to wget-orig
$ sudo cp /usr/bin/wget /usr/bin/wget-orig- Install the aria2stub package.
$ pip3 install aria2stubNow wget command runs the stub as default for the current user.
- Move the installed binary(default=/usr/local/bin/) to /usr/bin/.
$ sudo mv /usr/local/bin/wget /usr/bin/wget-stub- Use update-alternatives to set default binary.
$ sudo update-alternatives --install /usr/bin/wget wget /usr/bin/wget-orig 30
update-alternatives: using /usr/bin/wget-orig to provide /usr/bin/wget (wget) in auto mode
$ sudo update-alternatives --install /usr/bin/wget wget /usr/bin/wget-stub 40
update-alternatives: using /usr/bin/wget-stub to provide /usr/bin/wget (wget) in auto mode- Verify that wget-stub is default
$ sudo update-alternatives --config wget
There are 2 choices for the alternative wget (providing /usr/bin/wget).
Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/bin/wget-stub 40 auto mode
1 /usr/bin/wget-orig 30 manual mode
2 /usr/bin/wget-stub 40 manual mode
Press <enter> to keep the current choice[*], or type selection number:- The setup is ready, try using wget now.
- Copy original curl to curl-orig
$ sudo cp /usr/bin/curl /usr/bin/curl-orig- Install the aria2stub package.
$ pip3 install aria2stubNow curl command runs the stub as default for the current user.
- Move the installed binary(default=/usr/local/bin/) to /usr/bin/.
$ sudo cp /usr/local/bin/curl /usr/bin/curl-stub- Use update-alternatives to set default binary
$ sudo update-alternatives --install /usr/bin/curl curl /usr/bin/curl-orig 30
update-alternatives: using /usr/bin/curl-orig to provide /usr/bin/curl (curl) in auto mode
$ sudo update-alternatives --install /usr/bin/curl curl /usr/bin/curl-stub 40
update-alternatives: using /usr/bin/curl-stub to provide /usr/bin/curl (curl) in auto mode- Verify that curl-stub is default
$ sudo update-alternatives --config curl
There are 2 choices for the alternative curl (providing /usr/bin/curl).
Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/bin/curl-stub 40 auto mode
1 /usr/bin/curl-orig 30 manual mode
2 /usr/bin/curl-stub 40 manual mode
Press <enter> to keep the current choice[*], or type selection number:- The setup is ready, try using curl now.
- If command cannot be translated to aria2c equivalent, then it falls back to the corresponding program.
- Use --orig flag to use the original program.
- .curlrc is not supported as of now
- To revert back to using the original command(if followed optional approach), run the following command for wget(similarly for curl):
$ sudo update-alternatives --config wget- only files are supported for --cookie flag
