cp

I want to cp a directory but I do not want to overwrite any existing files even it they are older than the copied files. And I want to do it completely noniteractive as this will be a part of a Crontab Bash script. Any ideas? hovanessyan Taken from the man page : -n, --no-clobber do not overwrite an existing file (overrides a previous -i option) Example: cp -n myoldfile.txt mycopiedfile.txt Hans Ginzel Consider using rsync . rsync -a -v --ignore-existing src dst As per comments rsync -a -v src dst is not correct because it will update existing files. cp -n Is what you want. See the man page.

I suppose I could compare the number of files in the source directory to the number of files in the target directory as cp progresses, or perhaps do it with folder size instead? I tried to find examples, but all bash progress bars seem to be written for copying single files. I want to copy a bunch of files (or a directory, if the former is not possible). SteveLambert You can also use rsync instead of cp like this: rsync -Pa source destination Which will give you a progress bar and estimated time of completion. Very handy. To show a progress bar while doing a recursive copy of files & folders &

I need to copy all *.jar files from directory and all its subdirectories. How can I do it in UNIX/Linux terminal? Command cp -r *.jar /destination_dir doesn't work. rsync is useful for local file copying as well as between machines. This will do what you want: rsync -avm --include='*.jar' -f 'hide,! */' . /destination_dir The entire directory structure from . is copied to /destination_dir, but only the .jar files are copied. The -a ensures all permissions and times on files are unchanged. The -m will omit empty directories. -v is for verbose output. For a dry run add a -n, it will tell you

In bash I need to do this: take all files in a directory copy them into an existing directory How do I do this? I tried cp -r t1 t2 (both t1 and t2 are existing directories, t1 has files in it) but it created a directory called t1 inside t2, I don't want that, I need the files in t1 to go directly inside t2. How do I do this? Nick What you want is: cp -R t1/. t2/ The dot at the end tells it to copy the contents of the current directory, not the directory itself. This method also includes hidden files and folders. If you want to copy something from one directory into the current directory, do

This question already has an answer here: Linux: copy and create destination dir if it does not exist 19 answers When copying a file using cp to a folder that may or may not exist, how do I get cp to create the folder if necessary? Here is what I have tried: [root@file nutch-0.9]# cp -f urls-resume /nosuchdirectory/hi.txt cp: cannot create regular file `/nosuchdirectory/hi.txt': No such file or directory To expand upon Christian's answer, the only reliable way to do this would be to combine mkdir and cp : mkdir -p /foo/bar && cp myfile "$_" As an aside, when you only need to create a single

I have a list of certain files that I see using the command below, but how can I copy those files listed into another folder, say ~/test? find . -mtime 1 -exec du -hc {} + Ankur Adding to Eric Jablow's answer, here is a possible solution (it worked for me - linux mint 14 /nadia) find /path/to/search/ -type f -name "glob-to-find-files" | xargs cp -t /target/path/ You can refer to " How can I use xargs to copy files that have spaces and quotes in their names? " as well. Thiyagu ATR Actually, you can process the find command output in a copy command in two ways: If the find command's output doesn

Under unix, I want to copy all files with a certain extension (all excel files) from all subdirectories to another directory. I have the following command: cp --parents `find -name \*.xls*` /target_directory/ The problems with this command are: It copies the directory structure as well, and I only want the files (so all files should end up in /target_directory/) It does not copy files with spaces in the filenames (which are quite a few) Any solutions for these problems? --parents is copying the directory structure, so you should get rid of that. The way you've written this, the find executes,

I want to copy all files in a directory except some files in a specific sub-directory. I have noticed that 'cp' command didn't have a --exclude option. So, how can I achieve this? hank rsync is fast and easy: rsync -av --progress sourcefolder /destinationfolder --exclude thefoldertoexclude You can use --exclude multiples times. rsync -av --progress sourcefolder /destinationfolder --exclude thefoldertoexclude --exclude anotherfoldertoexclude Note that the dir thefoldertoexclude after --exclude option is relative to the sourcefolder , i.e., sourcefolder/thefoldertoexclude . Also you can add -n
