Question Automate "touch" bash script not working.
Code:
#!/bin/bash -i
SAVEIFS=$IFS
IFS=$"\n\b"

picc=$*
if [ -f "$picc" ]; then
echo $TDATE
if [ ! -z "$TDATE" ]; then
 touch dummy
 touch -t "tdate" dummy
 touch -r "dummy" "$picc"
else
    echo -e "No mod date value to apply. If there is one in your shell,\ninvoke \e[7msuperdate\e[0m and try again."
    exit 1
fi
fi
IFS=$SAVEIFS

Started asking advice on this (on Linuxquestions.org). The last time I ran the script, this happened.
the script, when I run it, is neither changing the date of the file pointed to nor creating the file "dummy." And the command in line 15 the script, when I run it, is neither changing the date of the file pointed to nor creating the file "dummy." And the command in line 15 isn't even returning an "empty variable" kind of error. In short, the script does nothing I can discern between running it and not running it.

Anyone care to advise me?

Read and write bits get set, but not the execute bit. Is there some gap in my understanding, or is... (2 Replies)
