imv foo
2014-01-24 01:34:01
User: denilsonsa
Tags: mv cp

icp and imv, interactive versions of cp and mv, will prompt the user for the new filename. These tools are from rename-utils package.

cp foo{,bak}
2014-01-22 14:09:42
Functions: cp
Tags: cp

Utilizes shell expansion of {} to give the original filename and a new filename as arguments to `cp`. Can easily be extended to make multiple copies.

buf () { oldname=$1; if [ "$oldname" != "" ]; then datepart="$(date +%Y-%m-%d).bak"; firstpart=`echo $oldname | cut -d "." -f 1`; newname=`echo $oldname | sed s/$firstpart/$firstpart.$datepart/`; cp -iv ${oldname} ${newname}; fi }
2012-08-15 08:31:44
User: juliushibert
Functions: cp cut sed

Appends the input file with the date format YYYY-MM-DD.bak. Also runs silently if you remove the -v on the cp at the end of the function.

cp -rf srcdir/* destdir
2012-06-25 13:01:03
User: jlaunay
Functions: cp
Tags: cp

As cp is often an alias to cp -i you can use \cp (or cp full path /bin/cp) to use the real cp command instead of its alias

cp -auv /SorceDirectory/ /ParentDestination/
2012-03-04 13:04:03
User: joeseggiola
Functions: cp

Backup a whole directory copying only updated files.

dpkg-repack firefox
2012-01-13 11:47:40
User: knoppix5

If any changes have been made to the package while it was unpacked (ie, conffiles files in /etc modi‐fied), the new package will inherit the changes.

This way you can make it easy to copy packages from one computer to another, or to recreate packages that are installed on your system, but no longer available elsewhere.

Note: dpkg-repack will place the created package in the current directory.

cp -r * .??* /dest
2011-12-16 23:41:03
User: atoponce
Functions: cp
Tags: mv rm cp

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):

cp -r {*,.??*} /dest

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 "..".

rename s/^/./ *
mv -b old_file_name new_and_already_existent_file_name
2011-09-08 23:57:15
User: ztank1013
Functions: mv
Tags: backup mv cp safe

Sometimes in a hurry you may move or copy a file using an already existent file name. If you aliased the cp and mv command with the -i option you are prompted for a confirmation before overwriting but if your aliases aren't there you will loose the target file!

The -b option will force the mv command to check if the destination file already exists and if it is already there a backup copy with an ending ~ is created.

cp --sparse=always <SRC> <DST>
2011-09-07 08:02:50
User: h3xx
Functions: cp

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:

dd if=/dev/zero bs=1M count=5 |cp --sparse=always /dev/stdin SPARSE_FILE
cp httpd.conf{,.bk}

User: ideivid
Functions: cp
Tags: backup cp

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

files -type f | xargs -n100 | while read l; do mkdir $((++f)); cp $l $f; done
2011-02-15 23:15:16
User: flatcap
Functions: cp mkdir read xargs

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 :-)

buf() { cp -v $1 ${1/${1%%.*}/$f-$(date +"%Y%m%d_%H%M%S")};}
buf() { f=${1%%.*};e=${1/$f/};cp -v $1 $f-$(date +"%Y%m%d_%H%M%S")$e;}
2010-12-15 09:50:04
User: unefunge
Functions: cp date

"infix" version in bash (4.x+)

Remove -v to make it silent.

BTW: The OP forgot to use "cat" and "nmap" ;-) I had a good laugh though.

buf () {oldname=$1; if [ "$oldname" != "" ]; then datepart=$(date +%Y-%m-%d); firstpart=`echo $oldname | cut -d "." -f 1`; newname=`echo $oldname | sed s/$firstpart/$firstpart.$datepart/`; cp -i ${oldname} ${newname}; fi }

User: Seebi
Functions: cp cut date sed

This backup function preserve the file suffix allowing zsh suffix aliases and desktop default actions to work with the backup file too.

buf () { cp $1{,$(date +%Y%m%d_%H%M%S)}; }
2010-12-14 14:02:03
User: unefunge
Functions: cp date

1. you don't need to prepend the year with 20 - just use Y instead of y

2. you may want to make your function a bit more secure:

buf () { cp ${1?filename not specified}{,$(date +%Y%m%d_%H%M%S)}; }

for i in ???.jpg; do mv $i $(printf %04d $(basename $i .jpg) ).jpg ; done

User: carlesso
Functions: basename mv printf
Tags: rename cp printf

Useful if you have a list of images called 1 2 3 4 and so on, you can adapt it to rewrite it as 4 (in this example) 0-padded number.

find ./ ! -name 'excludepattern' | xargs -i cp --parents {} destdir
2010-09-27 21:36:50
User: starchox
Functions: cp find xargs
Tags: find xargs cp

Preserve file structure when coping and exclude some file o dir patterns

cp -n <src> <dst>
yes n | cp -p -i -r <src> <dest>
dir='path to file'; tar cpf - "$dir" | pv -s $(du -sb "$dir" | awk '{print $1}') | tar xpf - -C /other/path
2010-01-19 19:05:45
User: starchox
Functions: awk dir du tar
Tags: copy tar cp

This may seem like a long command, but it is great for making sure all file permissions are kept in tact. What it is doing is streaming the files in a sub-shell and then untarring them in the target directory. Please note that the -z command should not be used for local files and no perfomance increase will be visible as overhead processing (CPU) will be evident, and will slow down the copy.

You also may keep simple with, but you don't have the progress info:

cp -rpf /some/directory /other/path
find . -iname "*.jpg" -print0 | tr '[A-Z]' '[a-z]' | xargs -0 cp --backup=numbered -dp -u --target-directory {location} &
