Once you are in terminal/command line, access the database/collection you want to use as follows: show dbs use <db name> show collections choose your collection and type the following to see all contents of that collection: db.collectionName.find() More info here on the MongoDB Quick Reference Guide.
Since only the shell knows how to run shell functions, you have to run a shell to run a function. You also need to mark your function for export with export -f, otherwise the subshell won’t inherit them: export -f dosomething find . -exec bash -c ‘dosomething “$0″‘ {} \;
Piping to another process (Although this WON’T accomplish what you said you are trying to do): command1 | command2 This will send the output of command1 as the input of command2 -exec on a find (this will do what you are wanting to do — but is specific to find) find . -name ‘*.foo’ -exec … Read more
You can use chmod with the X mode letter (the capital X) to set the executable flag only for directories. In the example below the executable flag is cleared and then set for all directories recursively: ~$ mkdir foo ~$ mkdir foo/bar ~$ mkdir foo/baz ~$ touch foo/x ~$ touch foo/y ~$ chmod -R go-X … Read more
Or without ( and the need to escape it: find . -not -name “*.exe” -not -name “*.dll” and to also exclude the listing of directories find . -not -name “*.exe” -not -name “*.dll” -not -type d or in positive logic 😉 find . -not -name “*.exe” -not -name “*.dll” -type f
The thing I’d found confusing about -prune is that it’s an action (like -print), not a test (like -name). It alters the “to-do” list, but always returns true. The general pattern for using -prune is this: find [path] [conditions to prune] -prune -o \ [your usual conditions] [actions to perform] You pretty much always want … Read more
A -exec command must be terminated with a ; (so you usually need to type \; or ‘;’ to avoid interpretion by the shell) or a +. The difference is that with ;, the command is called once per file, with +, it is called just as few times as possible (usually once, but there … Read more
find . -type f -printf ‘%T@ %p\n’ \ | sort -n | tail -1 | cut -f2- -d” ” For a huge tree, it might be hard for sort to keep everything in memory. %T@ gives you the modification time like a unix timestamp, sort -n sorts numerically, tail -1 takes the last line (highest … Read more
I think you’ll get what you want with the -maxdepth 1 option, based on your current command structure. If not, you can try looking at the man page for find. Relevant entry (for convenience’s sake): -maxdepth levels Descend at most levels (a non-negative integer) levels of direc- tories below the command line arguments. `-maxdepth 0′ … Read more
No need to find. If you are just looking for a pattern within a specific directory, this should suffice: grep -hn FOO /your/path/*.bar Where -h is the parameter to hide the filename, as from man grep: -h, –no-filename Suppress the prefixing of file names on output. This is the default when there is only one … Read more
