Windows 2>&1 redirection equivalent in Linux
Writes normal and error output to the same file.
2>&1 redirection
command > all.log 2>&1
command > all.log 2>&1
command > all.log 2>&1
Overview
What this command does
On Windows, "2>&1 redirection" is used to merge stdout and stderr. On Linux, the closest practical mapping shown here is "command > all.log 2>&1". Writes normal and error output to the same file. This reference is grouped under Terminal & Shell Scripting → Redirection.
Windows → Linux context
What changes when you use this on Linux?
Equivalent task, different tool
Windows 2>&1 redirection maps to command > all.log 2>&1 for this task. Treat this as a workflow mapping rather than a character-for-character syntax translation.
Portable across the compared distros
The Debian/Ubuntu, Fedora and Arch rows use the same command in this mapping. Package availability or defaults can still vary, so check the installed tool version when an option behaves differently.
For the broader concept behind this mapping, read Linux command-line basics.
