I may have asked this before but I'd really like to understand this and get a fix for it. Given the following script:
#!/bin/bash declare -i i=0 for x in 1 2 3; do let i=i+1 echo "item $x" done echo "Processed $i items" cat > /tmp/file <<END item 1 item 2 item 3 END declare -i i=0 cat /tmp/file | while read item; do let i=i+1 echo "Read $item" done echo "Processed $i items" rm -f /tmp/file I get the following output: $ test.sh item 1 item 2 item 3 Processed 3 items Read item 1 Read item 2 Read item 3 Processed 0 items The quesiton is why is the integer "i" reporting 0 items processed for the second loop? I know that it has to do with the fact that a pipe is involved. However, how can I code this so that "i" survives? -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
