Rename multiple files based on pattern in Unix

Question

There are multiple files in a directory that begin with prefix fgh  for example   fghfilea fghfileb fghfilec   I want to rename all of them to begin with prefix jkl  Is there a single command to do that instead of renaming each file individually

Using StringSolver tools  windows  amp  Linux bash  which process by examples   filter fghfilea ok fghreport ok notfghfile notok  mv --all --filter fghfilea jklfilea   It first computes a filter based on examples  where the input is the file names and the output  ok and notok  arbitrary strings   If filter had the option --auto or was invoked alone after this command  it would create a folder ok and a folder notok and push files respectively to them   Then using the filter  the mv command is a semi-automatic move which becomes automatic with the modifier --auto  Using the previous filter thanks to --filter  it finds a mapping from fghfilea to jklfilea and then applies it on all filtered files     Other one-line solutions  Other equivalent ways of doing the same  each line is equivalent   so you can choose your favorite way of doing it   filter fghfilea ok fghreport ok notfghfile notok  mv --filter fghfilea jklfilea  mv filter fghfilea ok fghreport ok notfghfile notok  auto --all --filter fghfilea  mv fghfilea jklfilea    Even better  automatically infers the file name filter fghfilea ok fghreport ok notfghfile notok  auto --all --filter  mv fghfilea jklfilea    Multi-step solution  To carefully find if the commands are performing well  you can type the following   filter fghfilea ok filter fghfileb ok filter fghfileb notok   and when you are confident that the filter is good  perform the first move   mv fghfilea jklfilea   If you want to test  and use the previous filter  type   mv --test --filter   If the transformation is not what you wanted  e g  even with mv --explain you see that something is wrong   you can type mv --clear to restart moving files  or add more examples mv input1 input2 where input1 and input2 are other examples  When you are confident  just type  mv --filter   and voil    All the renaming is done using the filter   DISCLAIMER  I am a co-author of this work made for academic purposes  There might also be a bash-producing feature soon

There are many ways to do it  not all of these will work on all unixy systems      ls   cut -c4-   xargs -I   mv fgh   jkl    The    may be replaced by anything you find convenient  You could do this with find -exec too but that behaves subtly different on many systems  so I usually avoid that for f in fgh   do mv   f     f fgh jkl   done   Crude but effective as they say      rename  s  fgh jkl   fgh   Real pretty  but rename is not present on BSD  which is the most common unix system afaik  rename fgh jkl fgh  ls   perl -ne  chomp  next unless -e   o       s fgh jkl   next if -e  rename  o        If you insist on using Perl  but there is no rename on your system  you can use this monster    Some of those are a bit convoluted and the list is far from complete  but you will find what you want here for pretty much all unix systems

Generic command would be find  path to files -name   lt search gt    -exec bash -c  mv  0   0  lt search gt   lt replace gt          where  lt search gt  and  lt replace gt  should be replaced with your source and target respectively  As a more specific example tailored to your problem  should be run from the same folder where your files are   the above command would look like  find   -name  gfh   -exec bash -c  mv  0   0 gfh jkl         For a  quot dry run quot  add echo before mv  so that you d see what commands are generated  find   -name  gfh   -exec bash -c  echo mv  0   0 gfh jkl

There are several ways  but using rename will probably be the easiest   Using one version of rename   rename  s  fgh jkl   fgh    Using another version of rename  same as Judy2K s answer    rename fgh jkl fgh    You should check your platform s man page to see which of the above applies

This is how sed and mv can be used together to do rename   for f in fgh   do mv   f    echo   f    sed  s  fgh jkl g    done   As per comment below  if the file names have spaces in them  quotes may need to surround the sub-function that returns the name to move the files to   for f in fgh   do mv   f     echo  f   sed  s  fgh jkl g     done

Using find  xargs and sed   find   -name  fgh   -type f -print0   xargs -0 -I    sh -c  mv         dirname        echo   basename         sed  s  fgh jkl g       It s more complex than  nik s solution but it allows to rename files recursively  For instance  the structure      -- fghdir         -- fdhfilea         -- fghfilea  -- fghfile  e  -- fghfilea  -- fghfileb  -- fghfilec  -- other      -- fghfile  e      -- fghfilea      -- fghfileb      -- fghfilec   would be transformed to this      -- fghdir         -- fdhfilea         -- jklfilea  -- jklfile  e  -- jklfilea  -- jklfileb  -- jklfilec  -- other      -- jklfile  e      -- jklfilea      -- jklfileb      -- jklfilec   The key to make it work with xargs is to invoke the shell from xargs

rename might not be in every system  so if you don t have it  use the shell this example in bash shell  for f in fgh   do mv   f     f fgh xxx   done

This worked for me using regexp   I wanted files to be renamed like this   file0001 txt - gt  1 txt ofile0002 txt - gt  2 txt  f i l e0003 txt - gt  3 txt   usig  the   a-z    0   0-9     regexp where    0-9     is a group substring to use on the rename command  ls -1   awk  match  0    a-z     0   0-9        arr    print   arr 0        arr 1     xargs  -l mv   Produces   mv file0001 txt 1 txt mv ofile0002 txt 2 txt mv f i l e0003 txt 3 txt   Another example   file001abc txt - gt  abc1 txt ofile0002abcd txt - gt  abcd2 txt   ls -1   awk  match  0    a-z     0   0-9       a-z      arr    print   arr 0        arr 2  arr 1     xargs  -l mv   Produces     mv file001abc txt abc1 txt   mv ofile0002abcd txt abcd2 txt    Warning  be careful

This script worked for me for recursive renaming with directories file names possibly containing white-spaces   find   -type f -name          while read fname  do     dirname  dirname   fname       filename  basename   fname       newname  echo   filename    sed -e  s     g       mv    dirname   filename     dirname   newname  done   Notice the sed expression which in this example replaces all occurrences of   with space   This should of course be replaced according to the specific needs

A generic script to run a sed expression on a list of files  combines the sed solution with the rename solution       bin sh  e  1 shift  for f in     do     fNew   echo   f    sed   e       mv   f    fNew   done   Invoke by passing the script a sed expression  and then any list of files  just like a version of rename   script sh  s  fgh jkl   fgh
