What command is used to export a file's content as CSV?

The command that correctly exports a file's content as CSV is awk -F, '{ print }' filename. The awk command is a powerful text processing tool in Linux that can manipulate and generate formatted text, including CSV (Comma-Separated Values) output.

In this context, the -F, option tells awk to treat commas as field separators, which is particularly relevant when dealing with CSV files, as they typically use commas to separate different fields or values. The command then uses the action { print } to output each line as it reads it, effectively preserving the structure of the CSV data. This allows for flexible processing of the raw data while ensuring that the output maintains the CSV formatting.

The other options do not provide a valid means to specifically export a file's content as CSV. The command cat filename simply outputs the content of the file to the standard output without any modification or formatting. The option csv-export filename does not reference a standard command available in Linux by default, and thus would not work in most environments. Lastly, convert filename csv suggests using a conversion process, but it does not specify a tool or correct syntax recognized by the command line for converting to CSV format, making
