rename multiple files from search output

woodstock · #1 (**permalink**) 12-24-2008

Variations of multiple renames seems to come up a lot but i can't find the answer to this situation.
Tidying up a directory where people rename files to .working, .bob, .attempt1 & so on.

what i am trying to do is: list the file type, & rename from ".whatever" to .fixed.
As the ".whatever" is rarely the same, it makes this a bit more than the normal rename all ".a's" to ".b's" if you get my drift.

For this particular list of example files i have come up with:

for i in `ls WLAN_* | egrep -v 'TRF|fixed' | cut -d "." -f1`;do mv $i.* $i.fixed;done

which appears to work fine but a tad "around the houses". I was hoping someone knew a better way/shorter command string.
Example files as follows:

1.sh
bla1.txt
bla2.csv
WLAN_20081128_00051453_01.TRF
WLAN_20081128_00051468_01.TRF
WLAN_20081128_00051469_01.TRF
WLAN_20081128_00051470_01.TRF
WLAN_clo_20081202_00051984_01.sg-working2
WLAN_clo_20081129_00051540_01.sg-working
WLAN_clo_20081129_00051580_01.sg-working
WLAN_clo_20081202_00052011_01.still_failed
WLAN_clo_20080923_00043115.done
WLAN_20081128_00051467_01.TRF
WLAN_20081128_00051466_01.TRF
WLAN_20081128_00051465_01.TRF
WLAN_20081128_00051454_01.TRF
WLAN_20081128_00051455_01.TRF
WLAN_20081128_00051456_01.TRF
WLAN_20081128_00051457_01.TRF
WLAN_20081128_00051458_01.TRF
WLAN_20081128_00051459_01.TRF
WLAN_20081128_00051460_01.TRF
WLAN_20081128_00051461_01.fixed
WLAN_20081128_00051462_01.fixed
WLAN_20081128_00051463_01.TRF
WLAN_20081128_00051464_01.TRF
WLAN_clo_20081222_00054519_01.test1-sg

Desired output ( but this was using my command as above)

1.sh
bla1.txt
bla2.csv
WLAN_20081128_00051453_01.TRF
WLAN_20081128_00051468_01.TRF

You can do something along the lines of :

Code:

ls WLAN_* | egrep -v 'TRF|fixed|.txt|.csv|.sh' | 
   while read file
      do 
         mv "$file" "${file%.*}".fixed
      done

Modify it to fit your needs.

Yep! quite like that. saves mucking around with a delimiter.
made a one liner out of it and worked fine.

ls WLAN_* | egrep -v '.fixed|.TRF'| while read file; do mv "$file" "${file%.*}".fixed; done

still quite long though. Just me being lazy i suppose. I like your use of the while loop.

With Perl:

Code:

perl -e'
  map {($n = $_) =~ s/[^.]+$/fixed/; rename $_, $n}
    grep !/\.(csv|sh|txt|TRF|fixed)$/, glob "*.*"
    '

Posting back my learnings from here

ls WLAN* is not needed - there is no need for a process to be spawned here just shell construct is sufficient here

Code:

for file_name in WLAN_*

How to select the *.txt files using Loops

Thanks to cfajohnson !

Thanks for your suggestions folks. Handy forum. I've not tried perl before but will have a read up. I think for the time being i will stick with the "for i" & "while" methods for this though.
