bash - Batch Renaming in Shell -

i have full list of files like,

    1066_hasoffers.apk.apk.txt             161_genesys.apk.apk.txt             231_attendance.apk.apk.txt       2956_bookingbug.apk.apk.txt       3394_sumall.apk.apk.txt        4306_vocus.apk.apk.txt          ..... 

and one-liner rename them (say).

       1066_hasoffers.txt                 161_genesys.txt                 231_attendance.txt           2956_bookingbug.txt           3394_sumall.txt            4306_vocus.txt              .... 

how can done ?

rename command can used:

rename 's/apk.apk.//' *.txt 

which remove apk.apk file names.

or can use loop in bash:

for in *.txt;  new=${i%apk.apk.txt}txt  mv "${i}" "${new}" done
