I'm writing a script that selects rows from files in a directory which contain patterns $f1, $f2 and $f3 and storing the lines that contain the pattern in a file I want to call as $file_$pattern.xls, for example file1_2.54 Ghz.xls.
#!/bin/bash
#my_script.sh to summarize p-state values
f1="2.54 Ghz"
f2="1.60 Ghz"
f3="800 Mhz"
for f in $f1 $f2 $f3
do
for file in *.txt
do
grep $f1 $file > ${file}_${f1}.xls
done
done
Kindly help me with the script.
Two things...
Something like this might work:
#!/bin/bash
#my_script.sh to summarize p-state values
f1="2.54 Ghz"
f2="1.60 Ghz"
f3="800 Mhz"
for f in "$f1" "$f2" "$f3"
do
for file in *.txt
do
grep "$f" "$file" > "${file}_${f}.xls"
done
done
You can do everything in the shell, no need grep or other external tools
#!/bin/bash
f1="2.54 Ghz"
f2="1.60 Ghz"
f3="800 Mhz"
for file in *.txt
do
while read -r line
do
case "$line" in
*"$f1"* )
echo "$line" >> "${file%txt}_${f1}.xls";;
*"$f2"* )
echo "$line" >> "${file%txt}_${f2}.xls";;
*"$f3"* )
echo "$line" >> "${file%txt}_${f3}.xls";;
esac
done < "$file"
done
instead of
for f in $f1 $f2 $f3
use
for f in {$f1,$f2,$f3}
and rename your $f1 in the inner loop!
