How to rename with prefix/suffix?

Question

How do I do mv original.filename new.original.filename without retyping the original filename?

I would imagine being able to do something like mv

Answer 1

Bulk rename files bash script

#!/bin/bash
# USAGE: cd FILESDIRECTORY; RENAMERFILEPATH/MultipleFileRenamer.sh FILENAMEPREFIX INITNUMBER
# USAGE EXAMPLE: cd PHOTOS; /home/Desktop/MultipleFileRenamer.sh 2016_
# VERSION: 2016.03.05.
# COPYRIGHT: Harkály Gergő | mangoRDI (https://wwww.mangordi.com/) 

# check isset INITNUMBER argument, if not, set 1 | INITNUMBER is the first number after renaming
if [ -z "$2" ]
    then i=1;
else
    i=$2;
fi

# counts the files to set leading zeros before number | max 1000 files
count=$(ls -l * | wc -l)
if [ $count -lt 10 ]
    then zeros=1;
else
    if [ $count -lt 100 ]
        then zeros=2;
    else
        zeros=3
    fi
fi

# rename script
for file in *
do
    mv $file $1_$(printf %0"$zeros"d.%s ${i%.*} ${file##*.})
    let i="$i+1"
done

In my case I have a group of files which needs to be renamed before I can work with them. Each file has its own role in group and has its own pattern.

As result I have a list of rename commands like this:

f=`ls *canctn[0-9]*`   ;  mv $f  CNLC.$f
f=`ls *acustb[0-9]*`   ;  mv $f  CATB.$f
f=`ls *accusgtb[0-9]*` ;  mv $f  CATB.$f
f=`ls *acus[0-9]*`     ;  mv $f  CAUS.$f

Try this also :

f=MyFileName; mv $f {pref1,pref2}$f{suf1,suf2}

This will produce all combinations with prefixes and suffixes:

pref1.MyFileName.suf1
...
pref2.MyFileName.suf2

Another way to solve same problem is to create mapping array and add corespondent prefix for each file type as shown below:

#!/bin/bash
unset masks
typeset -A masks
masks[ip[0-9]]=ip
masks[iaf_usg[0-9]]=ip_usg
masks[ipusg[0-9]]=ip_usg
...
for fileMask in ${!masks[*]}; 
do  
registryEntry="${masks[$fileMask]}";
fileName=*${fileMask}*
[ -e ${fileName} ] &&  mv ${fileName} ${registryEntry}.${fileName}  
done

You could use the rename(1) command:

rename 's/(.*)$/new.$1/' original.filename

Edit: If rename isn't available and you have to rename more than one file, shell scripting can really be short and simple for this. For example, to rename all *.jpg to prefix_*.jpg in the current directory:

for filename in *.jpg; do mv "$filename" "prefix_$filename"; done;
