textql:tldr:6bc5e

textql: Read data from `stdin`.
$ cat ${filename} | textql -sql "${SELECT * FROM stdin}"
try on your machine

This command is used to process the contents of a file using the textql tool. Here's an explanation of the command:

  1. cat ${filename}: The cat command is used to output the contents of the specified file (${filename} represents the variable holding the file name).

  2. |: This vertical bar character is a pipe symbol that is used to redirect the output of the preceding command (in this case, the file contents) to the input of the next command (textql).

  3. textql -sql "${SELECT * FROM stdin}": The textql command is a tool for executing SQL queries on plain text data. The -sql option is used to specify an SQL query to be executed. In this case, the query is ${SELECT * FROM stdin}, where ${} is used to denote a variable (in this case, the variable represents the file contents).

Overall, the command reads the contents of a file (using cat), redirects it to textql, and executes an SQL query (SELECT * FROM stdin) on that data.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
