How to Avoid intermediate files when pipe does nt work
problem with piping one output to another.Would like to avoid the intermediate file creation.The piping does nt work on places where files have been created and goes in an endless loop.
sed -e "s/^\.\///g" $LINE1| sed -e "s/_\([a-zA-Z]\)/kkk\1/g" > $file1
tr -s '_' ' ' < $file1| \
sort -n -k 1.1,1.1 -k 2.1,2.8 -k 3.1,3.6 | \
awk '{ arr[$1]=$0 } END {for (i in arr) { print arr[i] } }' | \
tr '_' ' ' | sort > $resultsfile
sed -e "s/ [ ]*/_/g" $resultsfile |sed -e "s/^_//g"|sed -e "s/_$//g"| \
grep -v "^$"|sed -e "s/kkk/_/g"| while read LINE4
do
process
done
