POSTCAT(1)

POSTCAT(1) 💖

okay bestie, gather round, because this is postcat from the General Commands Manual and she is literally the little key to the Postfix queue closet 🔑✨

---

✨ NAME ✨

postcat — show Postfix queue file contents 🎀

---

🦋 SYNOPSIS 🦋

postcat [-bdefhnoqv] [-c config_dir] [files...]

---

🌸 DESCRIPTION 🌸

so the postcat(1) command prints the contents of the named files in human-readable form. the files are expected to be in Postfix queue file format. and if you don't name any files on the command line? she just reads from standard input like a lil champ 🫶

by default, postcat(1) shows the envelope and message content, as if the options -beh were specified. want just the message content? specify -bh (Postfix 2.7 and later). iconic behavior tbh 💅

---

💅 OPTIONS 💅

• -b — Show body content. the -b option starts producing output at the first non-header line, and stops when the end of the message is reached.

This feature is available in Postfix 2.7 and later. ⭐

• -c config_dir — the main.cf configuration file is in the named directory instead of the default configuration directory. 🗂️
• -d — Print the decimal type of each record.
• -e — Show message envelope content.

This feature is available in Postfix 2.7 and later. ⭐

• -f — Prepend the file name to each output line.

This feature is available in Postfix 3.10 and later. ⭐

• -h — Show message header content. the -h option produces output from the beginning of the message up to, but not including, the first non-header line.

This feature is available in Postfix 2.7 and later. ⭐

• -o — Print the queue file offset of each record.
• -q — Search the Postfix queue for the named files instead of taking the names literally.

This feature is available in Postfix 2.0 and later. ⭐

• -r — Print records in file order, don't follow pointer records.

This feature is available in Postfix 3.7 and later. ⭐

• -s offset — Skip to the specified queue file offset.

This feature is available in Postfix 3.7 and later. ⭐

• -v — Enable verbose logging for debugging purposes. multiple -v options make the software increasingly verbose 📢
