I am using the tee command to output the compilation errors of a program into a file along with the terminal.
gcc hello.c | tee file.txt
This is the command I have used. The compilation errors are displayed on the terminal but they are not outputted in the file. How should I output the std errors into file?
With csh, tcsh, zsh or recent versions of bash, try
gcc hello.c |& tee file.txt
where
In other Bourne-like shells:
gcc hello.c 2>&1 | tee file.txt
In rc-like shells:
gcc hello.c >[2=1] | tee file.txt
In the fish shell:
gcc hello.c ^&1 | tee file.txt
2>&1 | instead.
(t)csh feature, also available in zsh and recently added to bash.
teeonly redirects stdout, compilation errors are presumably being output to stderr. See this post for more info on redirecting stderr withtee
