bash - remove date from filename but keep the file extension -



bash - remove date from filename but keep the file extension -

i have files these in directory called current_dir:

my data-file 2014-10.txt info file201409.txt

and want

my data-file.txt info file.txt

here tried

rename 's/ *[0-9]{4}-?[0-9]{2}.*$//' current_dir/*.txt

but removed .txt extension well.

i'm quite new linux, help me?

rename replaces matched part removing .*$ regular look keeps .txt

rename 's/ *[0-9]{4}-?[0-9]{2}//' current_dir/*.txt

examples

$ rename -n 's/ *[0-9]{4}-?[0-9]{2}//' *.txt rename(data file201409.txt, info file.txt) rename(my data-file 2014-10.txt, data-file.txt)

bash rename

ios8 - iOS custom keyboard - preserve state between appearances - i'm having performance problems custom keyboard i'm working on. loading words in spell correction tree takes quite bit of time. seems done each time keyboard appears - there way preserve state of keyboard? apps can suspend / resume etc - can't find documentation on how extensions, or if there's mechanism doing att all. thanks! you loading dictionary net or disk? first case nsuserdefaults, encoding (nscopying) options store info. can load in background. according docs, os typically kills extension process, so, think there no way prevent keyboard objects deallocation (you may utilize nskeydarchiver). ios8 ios-app-extension custom-keyboard
