How to quote each argument from gnu parallel?


How to quote each argument from gnu parallel?

This might help you Since your function is called print_last maybe it will be enough to simply get the last element:
code :
parallel -C "\|" echo {-1} :::: data.tsv
parallel -C "\|" -X print_last \"\"{}  :::: data.tsv

Bash shell scripting. Variable as argument. No quote vs double quote

Hope this helps Shell variables are expanded verbatim, so you should use the quoted option. Let's say your $HOME variable were equal to /Users/rocket spacer. In that case, it would be the difference between running rm -rf /Users/rocket spacer and rm -rf "/Users/rocket spacer". The first would try to remove two things: /Users/rocket and spacer in the current directory. The second option would do what you want, and remove the the directory /Users/rocket spacer. In general, when expanding a shell variable which represents a path, you should wrap it in quotes so you don't have to worry about the possibility of anything being misinterpreted.

wish of those help The problem was: R saw Sepal.Length, wt, len symbols so it tried to look in the current environment and evaluated them. Of course it resulted in errors as they were columns of a data frame. When you quoted them, R didn't try to evaluate and returned values as it saw those as strings.
If you replace list with base::alist or dplyr::vars or rlang::exprs, it should work
code :
# loading the needed libraries
library(rlang)
library(tidyverse)

# defining the function
tryfn <- function(data, x, y) {
  data <-
    dplyr::select(
      .data = data,
      x = !! x,
      y = !! y
    )

  # creating a data frame of means
  result_df <- data.frame(mean.x = mean(data$x), mean.y = mean(data$y))

  # return the data frame
  return(result_df)
}

# alist handles its arguments as if they described function arguments. 
# So the values are not evaluated, and tagged arguments with no value are 
# allowed whereas list simply ignores them. 

purrr::pmap(.l = list(
  data = list(iris, mtcars, ToothGrowth),
  x    = alist(Sepal.Length, wt, len),
  y    = alist(Sepal.Width, mpg, dose)
),
.f = tryfn)

#> [[1]]
#>     mean.x   mean.y
#> 1 5.843333 3.057333
#> 
#> [[2]]
#>    mean.x   mean.y
#> 1 3.21725 20.09062
#> 
#> [[3]]
#>     mean.x   mean.y
#> 1 18.81333 1.166667


purrr::pmap(.l = list(
  data = list(iris, mtcars, ToothGrowth),
  x    = dplyr::vars(Sepal.Length, wt, len),
  y    = dplyr::vars(Sepal.Width, mpg, dose)
),
.f = tryfn)

#> [[1]]
#>     mean.x   mean.y
#> 1 5.843333 3.057333
#> 
#> [[2]]
#>    mean.x   mean.y
#> 1 3.21725 20.09062
#> 
#> [[3]]
#>     mean.x   mean.y
#> 1 18.81333 1.166667

purrr::pmap(.l = list(
  data = list(iris, mtcars, ToothGrowth),
  x    = rlang::exprs(Sepal.Length, wt, len),
  y    = rlang::exprs(Sepal.Width, mpg, dose)
),
.f = tryfn)

#> [[1]]
#>     mean.x   mean.y

#>

#>    mean.x   mean.y
#> 1 3.21725 20.09062
#> 
#> [[3]]

this one helps. You are trying to access the list TskList from different threads without any synchronization. This can lead to any kind of problems.
Just do this:
code :
var tasks = dt.AsEnumerable().Select(row => Task.Run(() =>
    {
        try
        {
            // some http call
        }
        catch (Exception ex)
        {
            // rewrap the needed information into your custom exception object
            throw YourException(ex, row["ssub_msisdn"]);
        }
    });

// now you are at the UI thread
foreach (var t in tasks)
{
    try
    {
        await t;
    }
    catch (YourException ex)
    {
        AppendTextBox(ex.SsubMsisdn + ", Error: " + ex.InnerException.Message, txtBoxResponse);
    }
}
HttpClient client = new HttpClient(); // maybe configure it

async Task ProcessRow(Row row) // put here the correct type
{
    try
    {
        var str = await client.GetStringAsync(row[address]);
        AppendTextBox(str, txtBoxResponse);
    }
    catch (HttpRequestException ex)
    {
        AppendTextBox(row["ssub_msisdn"] + ", Error: " + ex.Message, txtBoxResponse);
    }
}

var tasks = dt.AsEnumerable().Select(row => ProcessRow(row));
await Yask.WhenAll(tasks);

I think the issue was by ths following , The script I am writing with parallel currently looks like this: , Use eval:
code :
seq ${2:-3} |
  parallel --tty -j0 eval sidplayfp -wch{}.wav '{=$_=join" ",map{"-u".$_}grep!/@{[seq()]}/,(1..total_jobs())=}' ${@:3} -q $1 '2>/dev/null'

this one helps. Since you have "exterior" double quotes, you're also going to have trouble with the awk $ variables. I'd break it into chunks:
