tilde

A security write-up warns that placing the tilde character in your PATH environment variable can be dangerous, since the shell expands it to the home directory of whichever user runs a command, not necessarily your own. This can lead to unexpected or attacker-controlled directories being searched for executables.

A blog post argues that including the tilde character (~) in file or directory paths can cause problems, since Unix shells expand tilde to the user's home directory, potentially breaking scripts and commands. The post is being shared among developers on technology forums, though it has drawn little discussion so far with no comments recorded.

A security-focused blog post by disconnect3d warns against including the tilde character in the PATH environment variable, explaining how tilde expansion can lead to unexpected or dangerous executable resolution on Unix-like systems. Developers on Hacker News are debating the pitfalls of shell expansion in PATH entries and sharing their own configuration habits.
