Let's say that I write some commands in a file let's say cmake although it doesn't need to be cmake run writing some commands in a text file. example

filename: cmake_command

cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo ../prject-src/ && make && make install

let's for simplicity say that the cmake_command file is located in a folder where if you run the command as is, things will start building.

I tried this command

for i in $(cat cmake_command); do echo $i; done

as a test but instead of printing out 1 whole line, it splits on each white space so I get a list of individual strings.

How could I reorganize this command to work so instead of getting

cmake 
-DCMAKE_BUILD_TYPE=RelWithDebInfo 
../prject-src/ 
&& 
make && make install

i'd get this output

cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo ../prject-src/ && make && make install

    I'm not sure what you're trying to do. Are you trying to print the cmake_command file line-by-line? If so, what is wrong with just cat cmake_command? – Joseph R. Dec 21 '15 at 1:09
  • have all command one line at a time, then run bash -e command_file, -e flag will ensure exit on first error. – Archemar Dec 21 '15 at 7:40

The most easy way would be:

while read i; do echo "$i"; done < cmake_command
  • Will this produce output that is different from cat cmake_command? – Joseph R. Dec 21 '15 at 1:10
