Executing GNU Parallel within a script
bash, gnu, gnu-parallel, parallel-processing
Solution
Apparently the `--tollef` switch (that does not support the `:::` syntax) gets enabled when you run it from a script.
You can fix it either by enabling the `--gnu` switch as with
parallel --gnu echo {} ::: A B C
Problem
The command `parallel echo {} ::: A B C` executed from the command line return the correct result, while when invoked within a bash script return the error: This is the script: ``` #script.bash #!/usr/bin/env bash parallel echo {} ::: A B C ``` This is the output: ``` bash script.bash /bin/bash: {}: command not found /bin/bash: ::: command not found /bin/bash: A: command not found /bin/bash: B: command not found /bin/bash: C: command not found ``` Any idea why and how to correctly call GNU parallel within a bash script?
