i have bash-function regularly use list files , directories in nice format. problem is, everytime execute function, takes 2-3 seconds till data listing finished.
as calling find command 2 times, takes double time. wanted ask, how can start both find commands thread in parallel , output. presume make function output load faster. wrong?
script :
function lsa { # function stat files , folders in current dir # takes first argument directory stat # if no directory supplied, current dir assumed if [ -z "$1" ];then dir="." else dir="$1" fi # print directories first printf "*** directories *** \n" find "$dir" -maxdepth 1 -type d ! -name "." -printf "%m %u %g " -exec du -sh {} \; 2> /dev/null # print non-directories second printf "*** files *** \n" find "$dir" -maxdepth 1 ! -type d ! -name "." -printf "%m %u %g " -exec du -sh {} \; 2> /dev/null } kindly let me know. thank you.
update
with changes :
*** directories *** [1] 6882 *** files *** [2] 6883 [1]- done find . -maxdepth 1 -type d ! -name "." -printf "%m %u %g " -exec du -sh {} \; 2> /dev/null > dirs [2]+ done find "$dir" -maxdepth 1 ! -type d ! -name "." -printf "%m %u %g " -exec du -sh {} \; 2> /dev/null > non-dirs // , files , dirs 1 after other without changes :
borg@borg-cube:~$lsa *** directories *** // directories *** files *** // files
you cannot have multi-threads multi-processes running 2 find commands in background , saving outputs different files. wait both find commands completion , concatenate outputs (dirs first).
this way...
find . -maxdepth 1 -type d ! -name "." -printf "%m %u %g " -exec du -sh {} \; 2> /dev/null > dirs & ... find "$dir" -maxdepth 1 ! -type d ! -name "." -printf "%m %u %g " -exec du -sh {} \; 2> /dev/null > non-dirs & ... wait cat dirs non-dirs .... ** update **
replace cat dirs non-dirs @ end with:
printf "*** directories *** \n" cat dirs printf "*** files *** \n" cat non-dirs
