Yes, thank you.

I just think it would be better if the cron would change the path for every script according to its location (and therefore the line cd /home/users/me wouldn't be necessarry)....

I would like to ask if cron when running a planned script changes the current folder for the script.

Thank you!

New commands: -nt, -ot, -ef

I've adjusted the code and it seems to speed up at least twice:


#!/bin/sh


# File: test.sh

Well yes, in fact without external commands I would be at a loss - it would be pretty much work


... and I thought right :-)))

Sure you're right -> one example of bad code for all:

I'm not sure what you exactly mean. I may use whatever command except test - I got the assignment this way.

Thank you! I like the solution :-)...

Franklin52: well, I use this solution often but it seems to me a little weird to create a temporary file and rename it right away. I would expect this line:


paste -d":" 'file1' 'file2' |...

Is in Unix a tool that could do this:

paste -d":" 'file1' 'file2' | special_save "file1" # so that file1 would be treated in a way that would prevent problems with race condition

I know it...

2jim: well, partly too, yes

@vbe: Well, sure, but I was talking more about shell commands.. about the interface

I was thinking about pros and cons of unix and about comparison Unix shell (bash) and unix commands with Windows PowerShell and its commands. I just would like to hear what do you mean about:
