Bash перенаправление не создает текстовый файл

0 голосов
/ 08 апреля 2020

У меня есть следующий код: 

RAN=$RANDOM
STDOUT="out${RAN}.txt"
STDERR="err${RAN}.txt"
Rscript ...solvers/script.r ${CONFIG_PARAMS} 1> ${STDOUT} 2> ${STDERR}

Получение следующей ошибки: 

error: out30304.txt: No such file or directory

Но не должна ли строка, начинающаяся с Rscript, создавать текстовый файл?

РЕДАКТИРОВАТЬ: многоточие на самом деле не присутствует в коде, он там, чтобы удалить ненужную информацию.

EDIT2: больше кода для контекста. Опять же, все пути сокращены для удобства чтения и безопасности:

Перенаправить стандартный вывод в файл STDOUT и стандартный вывод в файл STDERR: 

RAN=$RANDOM
STDOUT="out${RAN}.txt"
STDERR="err${RAN}.txt"
yourScript.r ${CONFIG_PARAMS} > ${STDOUT} 2>${STDERR}
...
