+# Command Line Length Limitations
+
+The other day I tried to run a remove command on the contents of a directory
+with a **LOT** of files.
+
+```
+$ rm images/*
+```
+
+Instead of deleting the contents of the directory, the following message was
+displayed:
+
+```
+/bin/rm: cannot execute [Argument list too long]
+```
+
+Bash wanted to expand the entire command before executing it. It was too
+long. But what is too long?
+
+It turns out that we can figure out the max length of commands with the
+following command:
+
+```
+$ getconf ARG_MAX
+```
+
+For me, the result is `262144`.
