- Some good ideas:
-
-
- EDITING
-
-
- The very common situation:
- $ mkdir documents
- $ cd documents
- can be abbreviated to:
- $ mk documents
- $ [CTRL-T] (inserts all but first word of previous line)
-
-
- Also very common:
- $ mv document document1
- $ mv document[CTRL-P]1
- The CTRL-P function duplicates the previous word on the command line
-
-
- You might have wondered what CTRL-N (leave current line) is good for.
- Assume, for example, you just typed
- $ rm dh1:graphics/lo-res/gorilla
- when it comes to your mind that would prefer to keep a copy of that pic on
- diskette. Many would now delete this command line. Being a smart guy, you
- do the following:
- $ [CTRL-N] (leaves this command line alone)
- $ co[CTRL-T] df0:
- $ [Up-Arrow][Up-Arrow] (gets back the command line you left)
-
-
- In case you don't know what history completion is:
- $ search *.c *.h makefile foobar
- $ ram:
- $ dir
- $ rm tmpfile
- Now if want to repeat the search command, enter
- $ se[Shift-Up-Arrow]
- which brings up the the last command that started with 'se'.
-
-
- If you want to delete the file
- $ rm dh2:comm/uucp/mail/junk/409
- and you're far away from that directory, enter
- $ ju[ESC-c]409 (enters the resulting path of cd ju)
-
-
- The same function is also usable for 'cd'. Assume you have several 'junk'
- directories:
- $ ju[ESC-c][CTRL-R][CTRL-R][CTRL-R]
- Like this you'll cycle through the junk directories. When you've got the
- right one, press enter.
-
-
- Assume there are the files comm1.c, comm2.c, and comm3.c as well as their
- corresponding .o files. You want comm3.c:
- $ co[Shift-Tab]1[Tab]
- Of course this is more useful with longer file names.
-
-
- You can tab file name expand any patterns, not only abbreviations. Assume
- you want to delete all .c files in the current directory but the last:
- $ rm *.c[ESC-Tab][CTRL-W]
- In addition, you get to see all the files once again before deleting them.
-
-
- Next one: You have entered:
- $ dir
- $ foreach i ( *.c ) "e >>ram:temp $i
- $ more ram:temp
- and you would like to execute the same three statements again, enter:
- $ [Up-Arrow][Up-Arrow][Up-Arrow][ESC-Return][CTRL-R][CTRL-R]
-
-
- I know that the editing is not very user friendly. This is because it's
- quite hard and troublesome to get raw keycodes from the console, and it's
- impossible to get them from a VT200 terminal. Therefore I had to stick
- with CTRL and ESC combinations. Once you have learnt them (some of them are
- similar to EMACS), you can save lots of typing.
-
-
- COMMANDS
-
-
- My advice here is clear: Use aliases, aliases, aliases. In order to be
- able to create them as quickly as possible, create an alias (e.g. 'le')
- that edits your login file, plus another one (e.g. 'lx'), that re-executes
- it. My login contains almost only aliases, everthing else I've put in
- 'firstlogin.sh'.
-
-
- If you don't like the default options of one command, you can add more of
- them using an alias:
- $ alias dir "dir -q
- From now on, blocks will no longer be displayed in 'dir'.
-
-
- If your aliases have arguments, e.g.
- $ alias sc "search *.c
- problems arise when you try to specify options. e.g. case sensitivity:
- $ sc -c "hello world
- this will obviously not work. That's what @pickopts is good for:
- $ alias sc "%a search @pickopts( $a ) *.c @pickargs( $a )
-
-
- Once you have more aliases, it is useful to keep them sorted. You might
- also document them: Create a file 'aliases.doc', and perform
- $ set _man aliases.doc csh.doc
- That way, you can document them in a separate file.
