You need to cp, mv, scp, ..., some files around from one place to another, and after having laboriously typed out the source path, you remember that the destination directory doesn't yet exist, and so the command will fail. So rather than killing the command line and starting over, just interpolate the results of creating the directory and echo its name. You could DRY this with a for; do; done, but that may be more trouble than it's worth.

You must spezify /where folder and / folder

If you have another camera you must experiment with Exif data (after -g and after grep) and mask of your photo files IMG_????.JPG

I have do it on Knoppix 6.7.0

You must have installed exiv2.

Backup a whole directory copying only updated files.

Certain Flash video players (e.g. Youtube) write their video streams to disk in /tmp/ , but the files are unlinked. i.e. the player creates the file and then immediately deletes the filename (unlinking files in this way makes it hard to find them, and/or ensures their cleanup if the browser or plugin should crash etc.) But as long as the flash plugin's process runs, a file descriptor remains in its /proc/ hierarchy, from which we (and the player) still have access to the file. The method above worked nicely for me when I had 50 tabs open with Youtube videos and didn't want to have to re-download them all with some tool.

When working with jailed environments you need to copy all the shared libraries to your jail environment. This is done by running ldd on a binary which needs to run inside the jail. This command will use the output from ldd to automatically copy the shared libraries to a folder of your choice.

You could do the following, however, brace expansion with {} is not defined in POSIX, and therefore not guaranteed to work in all shells. But, if it does, it's more convenient (although it's certainly not less typing):

Sometimes there are times when I need to cp(1), mv(1) or rm(1) files recursively, but don't want to traverse the previous directory by following ../../../../ etc out of the current directory. This command prevents that. The secret sauce is ".??*". The file globbing ensures that it must start with a dot, and be followed by at least two characters. So, three characters must exist in the filename, which eliminates "." and "..".

expand to:

cp /work/host/phone/ui/main.cpp /work/target/phone/ui/main.cpp

!#

The entire command line typed so far.

This causes cp to detect and omit large blocks of nulls. Sparse files are useful for implying a lot of disk space without actually having to write it all out.

You can use it in a pipe too:

preserve all except context and xattr. useful when moving a running system to a new partition.

Some people put spaces in filenames. Others have an $EDITOR environment variable set. This defaults to vim, but you can use whatever you wish: emacs, nano, ed, butterflies, etc.

Remember to backup everything before changing it so you can restore all to normal.

1) Find true type fonts;

2) Copy them to /usr/share/fonts/truetype;

3) Reload font information.

Bash function copies a file prefixed with a version number to a subdirectory

This is a BASH feature.

The above command will create a backup of "filename" called "filename.DATE", where DATE is the actual day in %Y%m%d (year, month and day numbers together) format.

Take a folder full of files and split it into smaller folders containing a maximum number of files. In this case, 100 files per directory.

find creates the list of files

xargs breaks up the list into groups of 100

for each group, create a directory and copy in the files

Note: This command won't work if there is whitespace in the filenames (but then again, neither do the alternative commands :-)

Smaller Code

Better Runtime

This will tighten up security for your box. The default value for PermitRootLogin sadly is 'yes'.

even shorter (infix) version.
