I want to read a file and save it in variable, but I need to keep the variable and not just print out the file.
How can I do this? I have written this script but it isn’t quite what I needed:
#!/bin/sh while read LINE do echo $LINE done <$1 echo 11111----------- echo $LINE
In my script, I can give the file name as a parameter, so, if the file contains “aaaa”, for example, it would print out this:
But this just prints out the file onto the screen, and I want to save it into a variable!
Is there an easy way to do this?
In cross-platform, lowest-common-denominator
sh you use:
#!/bin/sh value=`cat config.txt` echo "$value"
zsh, to read a whole file into a variable without invoking
#!/bin/bash value=$(<config.txt) echo "$value"
zsh to slurp a file would be considered a Useless Use of Cat.
Note that it is not necessary to quote the command substitution to preserve newlines.
