🎀 NAME 🎀

okay so this is DBCOLRENAME(1) from User Contributed Perl Documentation, and the main character is dbcolrename — change the names of columns in a fsdb schema. That's the whole vibe, bestie. Periodt. 💖

✨ SYNOPSIS ✨

dbcolrename OldName1 NewName1 [OldName2 NewName2] ...

🦋 DESCRIPTION 🦋

Dbcolrename changes the names of columns in a fsdb schema, mapping OldName1 to NewName1, and so on for multiple pairs of column names. Slay.

And note that it is valid to do "overlapping" renames like dbcolrename a b b a. Yes, bestie, that exact overlapping move is legal 💅.

🌸 OPTIONS 🌸

No non-standard options. Not a single non-standard one, periodt.

This module also supports the standard fsdb options:

  • -d — Enable debugging output. 🐛
  • -i or --input InputSource — Read from InputSource, typically a file name, or "-" for standard input, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects. 🫶
  • -o or --output OutputDestination — Write to OutputDestination, typically a file name, or "-" for standard output, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects. 💖
  • --autorun or --noautorun — By default, programs process automatically, but Fsdb::Filter objects in Perl do not run until you invoke the run() method. The --(no)autorun option controls that behavior within Perl. ⚙️
  • --help — Show help. 🆘
  • --man — Show full manual. 📖

🍓 SAMPLE USAGE 🍓

Input:

#fsdb account passwd uid gid fullname homedir shell
johnh * 2274 134 John_Heidemann /home/johnh /bin/bash
greg * 2275 134 Greg_Johnson /home/greg /bin/bash
root * 0 0 Root /root /bin/bash
# this is a simple database

Command:

cat DATA/passwd.fsdb | dbcolrename fullname first_last

Output:

#fsdb      account passwd  uid     gid     first_last      homedir shell
