Linux randomly deleted my file while compiling what do I do?

Question

gcc -L/root/Desktop - Wall -o prog3.c -pthread -lcopy
/usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/Scrt1.0: In function \'_start\': (.text+0x20): undefined          


        

Answer 1

Little addendum of your options in such scenario:

1. It was Git (or any other version control) repository. In such case, you can simply bring it from previous commit

2. Your editor/IDE has some back-up system. Sometimes I need to bring back a file I've thought was needless. For such case, my favourite text editor should have create already back-up file in appropriate location (e.g. $XDG_DATA_HOME/vim/backup in my case).

If none of above, but you still have previously correctly compiled binary file

3. You can try to decompile, but this process - even if successful - isn't lossless (e.g. code is basically spaghetti).

4. Had you compiled with -g flag, you could possibly retrieve the code from debug info.

5. You can at least de-assemble to Assembly code.
