I want to build a bash script that reads a file and produces some command line parameters. my input file looks like
20.83 0.05 0.05 __adddf3
20.83 0.10 0.05 __aeabi_fadd
16.67 0.14 0.04 gaussian_smooth
8.33 0.16 0.02 __aeabi_ddiv
I must detect and copy all the __* strings and turncate them into a command such as
gprof -E __adddf3 -E __aeabi_fadd -E __aeabi_ddiv ./nameof.out
So far I use
#!/bin/bash
while read line
do
if [[ "$line" == *__* ]]
then
echo $line;
fi
done <input.txt
to detect the requested lines but i guess, what i need is a one-line-command thing that i can't figure out. Any kind suggestions?
