This might be useful to someone even though it is only tangentially related to
BBEdit. I spent quite a bit of time (let’s not talk about the hours I spent
trying to subtract 86,400 seconds from the current date in seconds repeatedly.
I did get it working, but egads!) juggling bad ideas before I came up with
this solution.
I do quite a bit in the BBEdit shell worksheets and I often need to do is touch
files to update the date stamp and I have a situation where I have several
hundred files that I need to date stamp with today’s date, yesterdays date, etc
back for 3 years.
The file names are in the form “nn?n? Name of the file”
1 name of file 1
2 name of file 2
...
99 name of file 99
100 name of file 100
And I need to execute a touch command along the lines of:
touch -t 202004200000 "1 name of file 1"
touch -t 202004190000 "2 name of file 2"
...
touch -t 201912220000 "99 name of file 99"
touch -t 201912210000 "100 name of file 100”
This is the solution I came up with, finally. It does require that you install
dateutils on your Mac to get gdate (brew install dateutils)
touch -t `/usr/local/bin/gdate --date='today - 99 days' +'%Y%m%d0000’` "99 name
of file 99”
It is trivial to replace the 99 with the index number of the file. If the file
doesn’t have an index number, you can use Text => Add/Remove Line Numbers.
Hope this comes in handy for someone.
