What is the difference between:
cd /tmp
tar -cf - *.txt |gzip > tmp_txt.tar.gz
and
cd /tmp
mknod pipe p
gzip < pipe > /tmp/tmp_txt1.tar.gz &
tar -cf pipe *.txt
Apart from the fact that we have to create the pipe file manually, is there any difference in the performance of the two?... (5 Replies)

Can I please have some ideas on how to do a recursive grep with certain types of files? The file types I want to use are *.c and *.java.
I know this normally works with all files.
grep -riI 'scanner' /home/bob/ 2>/dev/null
Just not sure how to get it to work *.c and *.java files. (5 Replies)

gzgrep
GZGREP(1) General Commands Manual GZGREP(1)NAME
gzgrep, gzegrep, gzfgrep - search possibly compressed files for a regular expression
SYNOPSIS
gzgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
gzgrep is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep. If no file is speci-
fied, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and
fed to grep.
If gzgrep is invoked as gzegrep or gzfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, gzgrep
uses it as the grep program to be invoked. For example:
for sh: GREP=fgrep gzgrep string files
for csh: (setenv GREP fgrep; gzgrep string files)
