stdbuf:tldr:83b73
The command stdbuf --input=${512K} ${command}
sets the input buffer size for the specified ${command}
to 512KB.
stdbuf
is a command-line utility in Unix-like systems that allows you to modify the buffering operations for other commands. It can define the buffering behavior for input, output, or error streams of a command.
In the given command, --input=${512K}
specifies the input buffering size for ${command}
. Here, ${512K}
is a placeholder value representing 512KB (kilobytes) of buffer size. It's common to use units like K (kilobytes), M (megabytes), or G (gigabytes) to denote the buffer size.
${command}
represents the actual command to which you want to apply the buffering configuration.
So, by running this command, you ensure that ${command}
will have an input buffer size of 512KB.
