Shell command to rename multiple archives
 
Hello all,

I'm a Debian user. I do have 1148 txt archives with different names, and I want to change their names. More specificaly, I just want to delete 1 letter from the archives. The names are:

WFI_FM1_DB_OD_B13_G100_I25_20120227_R_M_1_002.txt
WFI_FM1_DB_OE_B14_G100_I75_20120227_R_M_1_002.txt
WFI_FM1_DB_OD_B15_G159_I50_20120227_R_R_5_006.txt
WFI_FM1_DB_OD_B15_G159_I50_20120227_R_R_4_005.txt
WFI_FM1_DB_OD_B13_G100_I25_20120227_R_M_2_003.txt
WFI_FM1_DB_OE_B14_G100_I75_20120227_R_M_2_003.txt

etc...and I want to delete that R.

Does anyone know how to do it in shell with one command??

Thanks!

Should be fairly easy. The "rename" command may or may not do what you want it to do - I've found it to vary wildly between different distros. See what "man rename" says. However, otherwise you should be able to run this:

Code:
for i in WFI_FM1*.txt; do
    mv $i $(echo $i | sed 's/_R\(_[^_]\+_[^_]\+_[^_]\+.txt\)$/\1/')
done;
I don't know exactly what defines the archives' names, but these are the assumptions I've made:
  • They all begin with WFI_FM1 and end in .txt
  • The _R that you want to remove is followed by "_<some characters>_<some characters>_<some characters>.txt".

If these two are true, then the code should do what you want it to do. Hope this helps,
