I am writing a command in the crontab file
длинная команда $(date +%Y%m%d%H%M%S) продолжение When cron starts execution, it sees only this part.
длинная команда $(date + all that after + he does not see.
How can this be overcome?

according to the documentation ( $ man 5 crontab or online ), the percent symbol % will be converted by cron into a newline character.
in order to avoid this, add a backsight character in front of each % symbol used:
... $(date +\%Y\%m\%d\%H\%M\%S) ...

- did as you wrote, but did not help, here’s how cron now sees the command
/usr/bin/vlc -vvv rtsp://111.222.333.444:554/h264/ch01/main/av_stream --sout=file/ts:/home/admin/web/site.com/public_html/source/recording-$()- Diefair - well, in general, in the original question you had no space between the program name (
date) and the first argument (+что-то-там). probably because the result of the command execution ($(...)) doesn’t : there is no such programdate+что-то-там- aleksandr barakin - if I launch this command simply in the console - everything works - Diefair
- maybe I'm not doing something. I just need a new unique file name to be generated each time the crown is executed - Diefair
- all right you do. only a space between the program name and the first parameter / option should be. not a
программа параметр, but aпрограмма параметр. notdate+\%Y..., butdate +\%Y...- aleksandr barakin
