Solve : how to assign the contents of a file to a variable? |
|
Answer» I have the following code: I have the following code: It is better to assign each token ( or LINE ) of file to an array element. Awk and shell does arrays easily. The following is a batch array: C:\test>type varforfile.bat Code: [SELECT]@echo off set n=1 setlocal enabledelayedexpansion for /f "tokens=1-7 delims=,=" %%a in (test.txt) do ( set /a n=!n! + 1 if !n!==15 goto end set var!n!=%%g echo var!n!=%%g ) :end echo outside of loop echo var12=%var12% Output: C:\test>varforfile.bat var2= 269338 var3= 263941 var4= 266663 var5= 265108 var6= 268421 var7= 269602 var8= 266973 var9= 266477 var10= 270655 var11= 266822 var12= 268137 var13= 267681 var14= 266535 outside of loop var12= 268137 C:\test>Quote resdir='/opt/mydir1/client/13.01/mydir2/commandline' That code could be for use on a Linux system It would help if the OP would indicate what OS he has.Now marvin is posting batch files in the Unix section! Quote from: Geek-9pm on May 18, 2010, 01:28:23 PM That code could be for use on a Linux system resdir='/opt/mydir1/client/13.01/mydir2/commandline' echo $resdir > /usr/me/myfile.txt The contents of myfile.tx was already assigned to a variable, resdir . The question does not MAKE sense. Unix allows the assignment with a set command: ( all that is needed is var=value ) resdir='/opt/mydir1/client/13.01/mydir2/commandline' |
