how to assign the contents of a file to a variable

[BRIANH]

I have the following code:

resdir='/opt/mydir1/client/13.01/mydir2/commandline'
echo $resdir > /usr/me/myfile.txt

I'd like to set the contents of /usr/me/myfile.txt to a variable. Is that possible?

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>

resdir='/opt/mydir1/client/13.01/mydir2/commandline'
echo $resdir > /usr/me/myfile.txt

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!

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'
