![]() ![]() You may want to use ! -type d with find to exclude directories from the output, or (better), look at the -exclude=PATTERN options to tar. for the current directory, so everything will be stored. Note that tar stores files recursively, and the first output of that find is. So flash_drive_data files were being included. flash_drive_data/index2/ask-sdk-core/dist/dispatcher/error/handler/ not -path './flash_drive_data*' -exec tar cfv '' + I was getting output including things like: This is the default when there is more than one file to search. It seemed like I did (with some unexpected behavior with grep as I explained above). If you have the options -H and -n available ( man grep is your friend): cat file foo bar foobar grep -H foo file file:foo file:foobar grep -Hn foo file file:1:foo file:3:foobar. not -path './flash_drive_data*' I was getting nothing related to flash_drive_data. Finally, the objective of what I was doing above was to make sure that when I ran find. Why? Then, when I did grep "**" I believe I got all the files (or at least I think I did). When I replaced grep "*flash*" with just grep "*", I expected to get all files returned by find, but I got none. ![]() The 3/flas at the end is being highlighted.Ģ.

There are a few things which I tried that are confusing me:ġ. not -path './flash_drive_data*' | grep "./*flash*" Other variables, like $PATH, really do have multiple values.I am running the following command in order to find all files/directories that do not have anything to do with "flash_drive_data": find. By convention, we talk about that variable’s value, but we really mean its first (and only) value. Some variables, like $PWD, only have one value. In fact, all variables in fish are really lists, that can contain any number of values, or none at all. If it had been two arguments, then name would have been a list of length 2. The set command above used quotes to ensure that Mister Noodle was one argument. This is how fish usually receives the values for things like $LANG, $PATH and $TERM, without you having to specify them again.Įxported variables can be local or global or universal - “exported” is not a scope! Usually you’d make them global via set -gx MyVariable SomeValue.įor more, see Exporting variables. And whatever started your terminal emulator also gave it some variables that it will then pass on unless it specifically decides not to. So if your terminal emulator starts fish, and it exports $LANG set to en_US.UTF-8, fish will receive that setting. This works the other way around as well! If fish is started by something else, it inherits that parents exported variables. It can also be unexported with -unexport or -u. > set -x MyVariable SomeValue > env | grep MyVariable MyVariable=SomeValue Running Commands ¶įish runs commands like other shells: you type a command, followed by its arguments.
