So you create a .bat file with a long list of arguments and it fails with a message:
“the input line is too long”
To avoid this, split your long single line into multitude of shorter lines separated by the caret character to mark the line break. Like this:
echo 1^ 2^ 3
You run a command on command line and receive a mysterious error message:
sh: 0: getcwd() failed: No such file or directory
Possible explanation is that the directory you were working in has been deleted by some other process and indeed just does not exist anymore. Move, for example by typing “cd”, and continue working elsewhere.
After (re-)installation of Apache2 the browser greets you with error 500 “Internal Server Error” and Apache2 error log file contains message “Invalid command ‘RewriteEngine’, perhaps misspelled or defined by a module not included in the server configuration”.
Well, you might want to enable mod_rewrite, which is disabled by default:
service apache2 restart
After (re-)installing PHP and attempting to run a script, you may see an error message saying “PHP Fatal error: Uncaught Error: Call to undefined function mb_strtoupper()”.
Well, you may be missing the php-mbstring extension to PHP. Simply install it by:
sudo apt-get install php-mbstring
The problem: HP LaserJet 2010 printer gets recognized by Linux Mint but fails to print.
- Remove all automatically installed printers
- sudo hp-setup -i
Let it download the HP plugin and accept defaults, then print test page (you must not be root or the print will fail).
This may happen after a crash.
Problem: You attempt to start your Thunderbird, but its GUI window does not show. You can see it running as a process in the background, but nothing else happens.
Cause: The problem may be caused by a surviving lock file in the user profile directory.
Solution: Navigate to .thunderbird in your user directory, select the appropriate profile directory and delete or remove file .parentlock therein.
To find paragraph breaks (i.e. the ASCII line feed character 0A hex) in LibreOffice, use the currency symbol “$” as the search string.
Make sure to look into “Other options” and check “Regular expressions” in the “Find & Replace” dialog.
By the way, searching for “\n” and replacing it with “\n” can be done only once, as on the repeated action there will be no matches found anymore and searching for “$” must be done instead. Read some more about this bug/feature/inconsistency here.
