	[test, fix] code to replace Menus - pinnL_pStrPL_replace()
	create code to :
		insert pth in : '<!--  [#!:/home/bill/web/fname:!#]  -->'
	cp Howell's *.html to "$d_webWork"'webPagesLocal/', replacing URL with pth in 1st line
	test use of "$d_webWork"'webPagesLocal/'
08Mar2023 def regexstr_tests iterative problem : incOne_create_seq( 0 1 c=0; c< )  
	should be ( 0 1 c ), 2 other ';for's work well...
14Sep2023 pOvrL_pStrPL_replace - should either [en, de]code [neither, both] [pOvr, pStrP]
28Sep2023 can I get ?I forget - in notes of something?
16Mar2024 povrL_pRgxP_replace(): in future, add options to pth file

For simple text replacement, all the work I've done to overcome the huge challenges of regExpr has been a waste of time.  Still essential for complex stuff, especially with chrCde. 
	chrCde = character encoding of sed problematic chrs ^$\&'",*.[]{}-\|/ (I question `/, which maybe OK?)
For almost all hyperlink work (most of what I do for webLocal), rpl should be much [bett, fast, clean]er.

Linux replace command
Updated: 06/01/2025 by Computer Hope
replace command

On Unix-like operating systems, the replace command makes modifications to strings of text in files or the standard input.

>> Howell: not in LinuxMint cmds, Software Manager (LMSW)
but LMSW does have : 
	jdReplace is a simple mass search and replace tool. You set a directory, a text to replace, the replacement and click OK. jdReplace will do the rest.
	>> Howell: I installed but immediately removed.  Can't see way to specify only one file? dangerous
		also, this is GUI, not command based!  (useless for me)
	Rpl is an intelligent search and replacement utility. It will change strings with new strings in multiple text files at the same time.  rpl can verify, find and edit several plain texts quickly.

03Dec2025 quick test:
14:03  3Dec2025$ rpl  -iF  '&",.*/\$^[]-{}|'  '<chrSedL>'  '/home/bill/web/bin/0_test/fileops/dOriginal/0_test/fileops/dOriginal/sedChrL problematic (copy).txt' 
rpl: The given filename patterns did not match any files!

14:09  3Dec2025$ rpl  '&",.*/\$^[]-{}|'  '<chrSedL>'  '/home/bill/web/bin/0_test/fileops/dOriginal/sedChrL problematic (copy).txt'  
rpl: Replacing "&",.*/\$^[]-{}|" with "<chrSedL>" (case sensitive; partial words matched)
rpl: Bad regex &",.*/\$^[]-{}| (unterminated character set)
~
14:09  3Dec2025$ rpl  '&,.*/\$^[]-{}|'  '<chrSedL>'  '/home/bill/web/bin/0_test/fileops/dOriginal/sedChrL problematic (copy).txt' 
rpl: Replacing "&,.*/\$^[]-{}|" with "<chrSedL>" (case sensitive; partial words matched)
rpl: Bad regex &,.*/\$^[]-{}| (unterminated character set)
~
>> I don't want regexpr!!!

14:12  3Dec2025$ rpl  -iF  '&,.*/\$^[]-{}|'  '<chrSedL>'  '/home/bill/web/bin/0_test/fileops/dOriginal/sedChrL problematic (copy).txt'

What is the max opened files limitation on Linux?

You can check the Soft limits and hard limits of your system by ulimit -a command.
    soft limits are simply the currently enforced limits.
    hard limits mark the maximum value which cannot be exceeded by setting a soft limit.
Soft limits could be set by any user while hard limits are changeable only by root. Limits are a property of a process. They are inherited when a child process is created so system-wide limits should be set during the system initialization in init scripts and user limits should be set during user login for example by using pam_limits.

There are often defaults set when the machine boots. So, even though you may reset your ulimit in an individual shell, you may find that it resets back to the previous value on reboot. You may want to grep your boot scripts for the existence ulimit commands if you want to change the default.

If the limitation was 1024, means you/process can open maximum 1024 files. if you exceed this limit means open, pipe and dup system calls will fail:

    RLIMIT_NOFILE:

    Specifies a value one greater than the maximum file descriptor number that can be opened by this process. Attempts (open(2), pipe(2), dup(2), etc.) to exceed this limit yield the error EMFILE.

	cd /path/to/your/folder
	sed -i 's/foo/bar/g' *
Occurrences of "foo" will be replaced with "bar".
On BSD systems like macOS, you need to provide a backup extension like -i '.bak' or else "risk corruption or partial content" per the manpage.
	cd /path/to/your/folder
	sed -i '.bak' 's/foo/bar/g' *

If you have list of files you can use
	replace "old_string" "new_string" -- file_name1 file_name2 file_name3
If you have all files you can use
	replace "old_string" "new_string" -- *
If you have list of files with extension, you can use
	replace "old_string" "new_string" -- *.extension
