See also i-search-fwd and history-search-backward. Any other character not bound to self-insert-command terminates the search, leaving the current line in the input buffer, and is then interpreted as normal input. In particular, a carriage return causes the current line to be executed.

NLS support differs depending on whether or not the shell was compiled to use the system’s NLS (again, see version). , the classification of which characters are printable) and sorting, and changing the LANG or LC_CTYPE environment variables causes a check for possible changes in these respects. In either case, 7-bit ASCII is the default character code (e. Native Language System support (+) The shell is eight bit clean (if so compiled; see the version shell variable) and thus supports character sets needing this capability. The watch and who shell variables can be set to report when selected users log in or out, and the log builtin command reports on those users at any time.

Unfortunately, slow-mouse problems still occur in Linux, especially when running LXDE. Currently, the best way to fix a slow mouse consists of these two tactics. Even more unfortunately, the Mouse: Fast and Accurate Mousing Under Linux is no longer applicable: Most setups no longer even have an /etc/XFConfig86-4 file.


By default, the mouse under Linux is typically much too slow, requiring large hand movements to move the pointer. Luckily, this problem is easy to fix. This is inconvenient, and although I’m a layman with regard to ergonomics, I personally fear those large hand movements put me at greater risk for repetitive motion injuries.

The abbreviations ‘%+’, ‘%’, and (by analogy with the syntax of the history mechanism) ‘%%’ all refer to the current job, and ‘%-’ refers to the previous job. In output pertaining to jobs, the current job is marked with a ‘+’ and the previous job with a ‘-’. The shell maintains a notion of the current and previous jobs.

In a guide like this one there are likely to be at least some. I would like to thank Lars and Joanna for their hard work on the guide.

Once you have the anchordir directory, you can have your way with the whole tree by appending directories as necessary to locate all components within the tree. Here’s how to do it in Python:. Assuming the executable is in the anchor directory and not below it, this is pretty easy, simply by assigning variable targetdir to the value of arg0, doing the proper stuff so it always ends with exactly one slash. The challenge is that the program can be called from anywhere in on the computer, but it must “know” its anchor directory.

It suffices to place the sequence of commands in ()’s to force it to a subshell, i. , ‘( a ; b ; c )’. If you suspend ‘b’, the shell will then immediately execute ‘c’. Shell builtin functions are not stoppable/restartable. Command sequences of the form ‘a ; b ; c’ are also not handled gracefully when stopping is attempted. This is especially noticeable if this expansion results from an alias.

Remaining arguments are placed in the argv shell variable. Login before instead of after /etc/csh. History (or the value of the histfile shell variable), then ~/. Tcshrc is not found, ~/. Tcshrc (+) or, if ~/. Cshdirs (or the value of the dirsfile shell variable) (+). The shell may read /etc/csh. Startup and shutdown A login shell begins by executing commands from the system files /etc/csh. History, if so compiled; see the version shell variable. Login, and finally ~/. It then executes commands from files in the user’s home directory: first ~/. Login before instead of after ~/.

) can be set to make backslashes always quote ‘#146;, ‘’’, and ‘”’. History substitution Each command, or ‘‘event’’, input from the terminal is saved in the history list. The previous command is always saved, and the history shell variable can be set to a number to save that many commands. Remember that substitutions can be prevented by quoting as described under Lexical structure. Substitutions We now describe the various transformations the shell performs on the input in the order in which they occur. The histdup shell variable can be set to not save duplicate events or consecutive duplicate events. (+) This may make complex quoting tasks easier, but it can cause syntax errors in csh(1) scripts. The backslash_quote shell variable (q. We note in passing the data structures involved and the commands and variables which affect them.

Similarly, saying ‘%1 &’ resumes job 1 in the background, just like ‘bg %1’. A job can also be named by an unambiguous prefix of the string typed in to start it: ‘%ex’ would normally restart a suspended ex(1) job, if there were only one suspended job whose name began with the string ‘ex’. It is also possible to say ‘%. There are several ways to refer to jobs in the shell. If you wish to refer to job number 1, you can name it as ‘%1’. The character ‘%’ introduces a job name. Just naming a job brings it to the foreground; thus ‘%1’ is a synonym for ‘fg %1’, bringing job 1 back into the foreground. String’ to specify a job whose text contains string, if there is only one such job.
