Rename files based on a list
Hi,
I have a directory with a lot of files like this:
Code:
a.bam
b.bam
c.bam

I like to rename these files based on a list where the name of the files in the first column will be replasced by the names in the second column. Here is my list which is a tab-delimited text file:
Code:
a    x
b    y
c    z

The output should be like this:
Code:
x.bam
y.bam
z.bam

Thanks in advance

Try:
Code:
while IFS='	' read from to
do
  [ -f "$from.bam" ] && mv -- "$from.bam" "$to.bam"
done < list

where the TAB Character can entered as CTRL-V TAB in vi..

Or
Code:
tab=$(printf "\t")
while IFS=$tab read from to
do
  [ -f "$from.bam" ] && mv -- "$from.bam" "$to.bam"
done < list

In bash of ksh93 you can use $'\t'

Shouldn't the line marked in red above be:
Code:
while IFS="$tab" read from to

?

Hi Don, it is a variable assignment and $tab is therefore exempt from field splitting after expansion...
