I like to use ripgrep, like its format and colors.
For example:
find ./ -name "*" -type f -size -20k| xargs rg -n -C2 "index"
or
find ./ -name "*" -type f -size -20k| xargs rg -n -C2 2>/dev/null "index"
But it may not be available in Ubuntu 12.04. To write a script to execute grep,
you can get output similar to ripgrep. Unlike ripgrep, the file name is printed on the bottom line. As follows:
find ./ -name "*" -type f -size -20k| while read file; do if grep -n -C2 "index" $file; then echo -e "\033[35m $file\n \033[0m"; fi done
Filter out "No such file or directory" messages:
find ./ -name "*" -type f -size -20k| while read file; do if grep -s -n -C2 "index" $file; then echo -e "\033[35m $file\n \033[0m"; fi done
You can also write a script to improve grep:
cd ~/
vi impgrep
#!/bin/sh
while read file; do if grep --color=auto "$@" $file; then echo -e "\033[35m $file\n \033[0m"; fi done
chmod 755 impgrep
Usage example:
find ./ -name "*.c" -o -name "*.h"|~/impgrep -s -n -C2 "index"
