sed/shell scripting - add line if needed and not allready there
I am writing a shell script that checks all .c files to see if they use fprintf or printf. If a file does, then the line #include <stdio.h> is added to the top of the file, unless it's already there. This is what I've got: Code:
#!/bin/sh egrep -l f?printf *.c | while read file; do sed -i '1i\ #include <stdio.h>' $file; done The problem is that it doesn't check to see if <stio.h> is allready there, so I've been thinking about using Code:
egrep -l f?printf *.c | grep -L '#include <stdio.h> but this doesn't work because it anonimizes the files when I use the pipe. Last edited by computethis; 4 Weeks Ago at 03:07 AM.. Reason: added code tags |
