linux - Using Shell, How can I read one text file's value and enter it into running crontab as input? -

i want run 1 cronjob in need supply input. input have 1 text file. how can read text file data , supply input cronjob?

i running 1 cron job .sh file. needs input data 2-3 times while running. data stands text1.txt, text2.txt, etc.

now, want read data these text files , insert input in running cronjob. crontab file execution waits "expect" command. , expects data go ahead, , data residing in text file.

so if understand correctly, run script cronjob; somewhere in script can say:

x=`cat file` 

or can add cat file | grep something 1 line file

and later use $x expected input.
