Find files with certain extensions

findregular expression

How can I use find to find all files that have a .xls or .csv extension? I have seen a -regex option but I don't know how to use it.

Best Answer

Why not simply use this:

find -name "*.xls" -o -name "*.csv"

You don't need regex for this.

If you absolutely want to use regex simply use

find -regex ".*\.\(xls\|csv\)"

How to find files not of a certain type

You wrote (redundant parentheses added for clarity):

find zUnorganized/ \( -not -iname "*.mp3" -and -not -iname "*.flac" -and -not -iname "*.MP3" -and -not -iname "*.wav" \) \
               -or \( -not -iname "*.m4a" -and -not -iname "*.jpg" \)

Either use -and -not throughout, or use or throughout and finish with -print (meaning: do nothing for this, otherwise do nothing for that, etc, otherwise print). You'll also want to limit the search to regular files, otherwise directories will be listed.

find zUnorganized/ -type f -not -iname "*.mp3" -and -not -iname "*.flac" -and -not -iname "*.MP3" -and -not -iname "*.wav" -and -not -iname "*.m4a" -and -not -iname "*.jpg"
find zUnorganized/ \! -type f -o \
                   -iname "*.mp3" -o -iname "*.flac" -o -iname "*.MP3" -o -iname "*.wav" -o -iname "*.m4a" -o -iname "*.jpg" -o \
                   -print

CentOS Files – How to Rename All Files with a Certain Name

rename stringx stringy stringx.*

There are (at least) two utilities called rename on typical Linux systems. Debian and derived distributions (including Ubuntu) ship a Perl script whose syntax would be

rename 's/stringx/stringy/' stringx.*

On other distributions, including CentOS, rename is from util-linux, and its syntax is what I wrote above. This utility is available under the name rename.ul on Debian and derivatives.

If you want to recurse in subdirectories, assuming that by csh you mean tcsh (but really, think of entering the mid-1990s and switching to zsh):

set globstar
rename stringx stringy stringx.* **/stringx.*
