Hi,
Can the pre-commit hook accept user input? I'm new to linux and bash
scripting and here's what I'm trying. (It appears to work in a manually
executed script.) The 'read' commands do not let me input anything when
running in a hook. (I've inserted a non-loop test at the beginning to be
sure.) The script just keeps going with a value of 'nothing' in the input
variable. This, of course, causes and endless loop in the code that I
really want to use.
#!/bin/bash
#*******************************************************************************
#* PGM NAME: pre-commit A hook script to verify what is about to be

#* should exit with non-zero status after issuing an
