bash - Editing my If statement also ideas about to grab a files date then move file - 


 gnu nano 2.2.6                           file:     years.sh                                                              #!/bin/bash  # when match not found, present nothing. shopt -s nullglob  # match .wav files containing date format. files=(*[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]*.wav)  if [[ ${#files[@]} -eq 0 ]];   echo "no file" fi     file in "${files[@]}"; # date part part file_date='' # sleep parts. ifs="-." read -ra parts <<< "$file" t in "${parts[@]}";         # break loop if match found     if [[ $t == [0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9] ]];         file_date=$t         break     fi done # if value not assigned, show error message , continue next file. # making sure there nothing in array , date before moves on

before adding if statement if worked perfect files have yyyymmdd.wav format.

if [[ -z $file_date ]];  # print $6 print $5 or $7 depending on os  another_file_date=`ls -l --time-style=long-iso | awk '{print $6}' | tr -d '-'`  file_year=${file_date:0:4} file_month=${file_date:4:2}    mkdir -p "$file_year/$file_month"  echo "moving: ./"$file "to: " "./"$file_year"/"$file_month mv  "$file" "$file_year/$file_month"      continue fi

end of new statement

file_year=${file_date:0:4} file_month=${file_date:4:2}     mkdir -p "$file_year/$file_month"  # -- there not interpret filenames starting - options.  echo "moving: ./"$file "to: " "./"$file_year"/"$file_month mv  "$file" "$file_year/$file_month" done

when run code no error not move meetme files. have file called meetme93238927832783.wav... wanna grab modify date or when file created , move mive dir year/month. when run code says no file first if statement.... before added new if statement work fine yyyymmdd.wav format

modify part of script file (the if , continue part) following, 

if [[ -z $file_date ]];     # print $6 print $5 or $7 depending on os      another_file_date=`ls -l --time-style=long-iso | awk '{print $6}' | tr -d '-'`      file_year=${file_date:0:4}     file_month=${file_date:4:2}     file_day=${file_date:6:2}       mkdir -p "$file_year/$file_month"      echo "moving: ./"$file "to: " "./"$file_year"/"$file_month     mv  "$file" "$file_year/$file_month"${file_year}${file_month}${file_day}.wav"     continue fi

and make sure print $6 correct (this test on linux, on solaris or aix number 6 should different).
