Chapter 2. Tcl—Introduction And Overview > Working With Files
2.14. Working With Files
Tcl has commands for accessing files. The open command opens a file. The second argument determines how the file should be opened. "r" opens a file for reading; "w" truncates a file and opens it for writing; "a" opens a file for appending (writing without truncation). The second argument defaults to "r".
open "/etc/passwd" "r" open "/tmp/stuff.[pid]" "w"
