Can anyone please inform me, how to save output of a C program to a text file without distorting the indentations? I have tried using ">" and using the "logsave" command but in both case the indentations of output changes. I have tried manipulating the output by using tabspaces and whitespaces but still the problem remains. Is there a way that the output is saved correctly? Output:

            +   ------  -------     +   ------  -------     +
Cache       |      L1D              |      L1D              |

            +   ------  -------     +   ------  -------     +

            +   ------  -------     +   ------  -------     +

Cache       |       L2              |       L2              |

            +   ------  -------     +   ------  -------     +

            +   ------  ------- ------- -------     +   

is the output coming on the terminal and when saved to the text file it changes to :

            +   ------  -------     +   ------  -------     +   
Cache       |      L1D              |      L1D              |

Answer 1

You could convert all tabs in the output of your program to spaces.

Try this:

./prog | expand > log-file
