Find multiple files and rename them in Linux

Question

I am having files like a dbg txt  b dbg txt     in a Suse 10 system  I want to write a bash shell script which should rename these files by removing   dbg  from them   Google suggested me to use rename command  So I executed the command rename  dbg txt  txt  dbg  on the CURRENT FOLDER  My actual CURRENT FOLDER contains the below files   CURRENT FOLDER a dbg txt CURRENT FOLDER b dbg txt CURRENT FOLDER XX c dbg txt CURRENT FOLDER YY d dbg txt   After executing the rename command    CURRENT FOLDER a txt CURRENT FOLDER b txt CURRENT FOLDER XX c dbg txt CURRENT FOLDER YY d dbg txt   Its not doing recursively  how to make this command to rename files in all subdirectories  Like XX and YY I will be having so many subdirectories which name is unpredictable  And also my CURRENT FOLDER will be having some other files also

If you just want to rename and don t mind using an external tool  then you can use rnm  The command would be    on current folder rnm -dp -1 -fo -ssf   dbg  -rs    dbg        -dp -1 will make it recursive to all subdirectories   -fo implies file only mode   -ssf   dbg  searches for files with  dbg in the filename   -rs    dbg    replaces  dbg with empty string   You can run the above command with the path of the CURRENT FOLDER too   rnm -dp -1 -fo -ssf   dbg  -rs    dbg     path to the directory

You can use find to find all matching files recursively     find   -iname   dbg   -exec rename  dbg txt  txt             EDIT  what the      and    are   The -exec argument makes find execute rename for every matching file found       will be replaced with the path name of the file  The last token     is there only to mark the end of the exec expression   All that is described nicely in the man page for find    -exec utility  argument                 True if the program named utility returns a zero value as its          exit status   Optional arguments may be passed to the utility           The expression must be terminated by a semicolon           If you          invoke find from a shell you may need to quote the semicolon if          the shell would otherwise treat it as a control operator   If the          string        appears anywhere in the utility name or the argu-          ments it is replaced by the pathname of the current file           Utility will be executed from the directory from which find was          executed   Utility and arguments are not subject to the further          expansion of shell patterns and constructs
