Renaming files

ksushants · 03-09-2012, 01:37 AM

Hi All,

I have a requirement to rename files:
Here we have to change the tco.out files to acw.out.

For E.G.: detco011tco.out should be renamed as deacw011.out.The other countries are FR,GB,ES,IT,NL &BE.

I have done it by:
a=detco011tco.out
x=`echo $a |cut -c1,2`
y=`echo $a |cut -c6-8`
z=`echo $a |cut -c12-15`
b=$x'acw'$y$z
mv $a $b

Is there any better and simpler way to do it? single command using SED?

Correct me if I'm wrong, as I am not sure that I understand your question very well.
I think that you can do it by:
A=detco011tco.out mv $A $(echo $A | sed 's/tco.out/.out/')

Hi,

Like TKH, I'm not entirely clear about your wishes.

Assuming this is your input:

Code:

# ls -l
total 0
-rw-r----- 1 druuna internet 0 Mar  9 08:54 betco033tco.out
-rw-r----- 1 druuna internet 0 Mar  9 08:54 detco011tco.out
-rw-r----- 1 druuna internet 0 Mar  9 08:54 nltco022tco.out

Running this code:

Code:

for THISFILE in *tco.out; do mv $THISFILE $(echo ${THISFILE/tco/acw} | sed 's/tco//'); done

You will end up with this:

Code:

$ ls -l
total 0
-rw-r----- 1 druuna internet 0 Mar  9 08:54 beacw033.out
-rw-r----- 1 druuna internet 0 Mar  9 08:54 deacw011.out
-rw-r----- 1 druuna internet 0 Mar  9 08:54 nlacw022.out

betco033tco.out changes to beacw033.out (first tco is changed to acw, second tco is removed).

Hope this helps.
