Some usefull functions to execute some bash code in R
Execute command as sudo
set_sudo("secret_sudo_password")
sudo("ls")Useful to test the lambda for looping functions from the map family:
input <- c("a" = 1, "b" = 2, "c" = 3)
input %>% bashR::simule_map(1)
#> [1] 1
cat(".x is now: ", .x, "\n")
#> .x is now: 1
cat(".y is now: ", .y, "\n")
#> .y is now: a
input %>% bashR::simule_map(3)
#> [1] 3
cat(".x is now: ", .x, "\n")
#> .x is now: 3
cat(".y is now: ", .y, "\n")
#> .y is now: c
input %>%
purrr::iwalk(~{cat("Value", .x, "is named", .y, "\n")})
#> Value 1 is named a
#> Value 2 is named b
#> Value 3 is named cParse a request, that was copied in chrome from DevTools > Network
