on-download-complete can't work with aria2

Question

i am not root user,so i install aria2-1.34.0 with ./configure --prefix=/home/xxx/.local, everything works fine but on-download-complete

i set on-download-complete=/home/xxx/aria2/a.sh

#!/bin/bash
echo 123 > 1.txt

when a task download completed, the log shows everything is ok

Answer 1

Accroding to the official document

-D, --daemon [true|false]

Run as daemon. The current working directory will be changed to / and standard input, standard output and standard error will be redirected to /dev/null. Default: false

You should modify /home/xxx/aria2/a.sh to

#!/bin/bash
echo 123 > $(dirname $0)/1.txt

to write the output to the right place.

Answer 2

got a solution for me

put --on-download-complete in cmd instead of aria2.conf

just run aria2 like:

aria2c --conf-path=/xxx/xxx/arai2.conf --on-download-complete=/xxx/xxx/xxx.sh -D

and it works

but i have no idea why it didn't work if set --on-download-complete in conf file
