🚀 Quick Reference

Use Case	Command	Description
Set a specific security context	chcon CONTEXT FILE	📄 Assign the given CONTEXT to FILE
Copy context from a reference file	chcon --reference=RFILE FILE	📋 Use RFILE's security context for FILE
Recursively change context	chcon -R CONTEXT DIR	🔄 Change context of all files under DIR
Set specific components	chcon -u USER -r ROLE -t TYPE -l RANGE FILE	👤🎭🏷️📏 Set user, role, type, or range individually

📝 SYNOPSIS

chcon [OPTION]... CONTEXT FILE...
chcon [OPTION]... [-u USER] [-r ROLE] [-l RANGE] [-t TYPE] FILE...
chcon [OPTION]... --reference=RFILE FILE...

📄 DESCRIPTION

Change the SELinux security context of each FILE to CONTEXT. With --reference, change the security context of each FILE to that of RFILE.

Also see Common options.

⚙️ OPTIONS

• --dereference — 🗂️ Do not affect symbolic links but what they refer to; this is the default.
• -h, --no-dereference — 🔗 Affect the symbolic links themselves instead of any referenced file.
• --reference=RFILE — 📄 Use RFILE’s security context rather than specifying a CONTEXT value.
• -R, --recursive — 🔄 Operate on files and directories recursively.
• --preserve-root — 🛡️ Refuse to operate recursively on the root directory, /, when used together with --recursive. (See Treating / specially)
• --no-preserve-root — ⚠️ Do not treat the root directory, /, specially when operating recursively; this is the default. (See Treating / specially)
• -H — ➡️ If --recursive (-R) is specified and a command line argument is a symbolic link to a directory, traverse it. (See Traversing symlinks)
• -L — ➡️ In a recursive traversal, traverse every symbolic link to a directory that is encountered. (See Traversing symlinks)
• -P — 🚫 Do not traverse any symbolic links. This is the default if none of -H, -L, or -P is specified. (See Traversing symlinks)
• -v, --verbose — 📢 Output a diagnostic for every file processed.
• -u USER, --user=USER — 👤 Set user USER in the target security context.
• -r ROLE, --role=ROLE — 🎭 Set role ROLE in the target security context.
• -t TYPE, --type=TYPE — 🏷️ Set type TYPE in the target security context.
• -l RANGE, --range=RANGE — 📏 Set range RANGE in the target security context.
