User input not reading correctly in bash -


i have data that's held in 1 of 3 directories , wanted create loop allow user access data.

i'm trying make loop work if enters 1-3 reads number , changes variable timeperiod either "daily", "bars10s", or "bars100ms". when echo timecheck , timeperiod variables when running code see if they're ok, timecheck comes right, timeperiod reads "daily" no matter timecheck variable reads as. i'm pretty new bash, appreciated.

#!/bin/bash  echo   timeperiod="" timecheck=0  read -p "time period fac run(press 1 daily, 2 10 sec  intervals, 3 100ms intervals): " -e -i "$timecheck" timecheck  if [ $timecheck==1 ] ;     timeperiod="daily" elif [ $timecheck==2 ] ;     timeperiod="bars10s"     elif [ $timecheck==3 ] ;     timeperiod="bars100ms" else     echo "not valid time period. please re-try." fi   echo $timecheck echo $timeperiod

you can use select - menus this.

ps3="select want>" select answer in "daily period" "10 sec period" "100 ms" "exit program" case "$reply" in     1) timeperiod="daily" ; break;;     2) timeperiod="10s" ; break;;     3) timeperiod="100ms" ; break;;     4) exit ;; esac done  echo "$timeperiod"

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
