5. Using bzip2 with less
To uncompress bzip2'd files on the fly, i.e. to be able to use "less" on them without first bunzip2'ing them, you can make a lesspipe.sh (man less) like this:
#!/bin/sh # This is a preprocessor for 'less'. It is used when this environment # variable is set: LESSOPEN="|lesspipe.sh %s" case "$1" in *.tar) tar tvvf $1 2>/dev/null ;; # View contents of various tar'd files *.tgz) tar tzvvf $1 2>/dev/null ;; # This one work for the unmodified version of tar: *.tar.bz2) bzip2 -cd $1 $1 2>/dev/null | tar tvvf - ;; #This one works with the patched version of tar: # *.tar.bz2) tyvvf $1 2>/dev/null ;; *.tar.gz) tar tzvvf $1 2>/dev/null ;; *.tar.Z) tar tzvvf $1 2>/dev/null ;; *.tar.z) tar tzvvf $1 2>/dev/null ;; *.bz2) bzip2 -dc $1 2>/dev/null ;; # View compressed files correctly *.Z) gzip -dc $1 2>/dev/null ;; *.z) gzip -dc $1 2>/dev/null ;; *.gz) gzip -dc $1 2>/dev/null ;; *.zip) unzip -l $1 2>/dev/null ;; *.1|*.2|*.3|*.4|*.5|*.6|*.7|*.8|*.9|*.n|*.man) FILE=`file -L $1` ; # groff src FILE=`echo $FILE | cut -d ' ' -f 2` if [ "$FILE" = "troff" ]; then groff -s -p -t -e -Tascii -mandoc $1 fi ;; *) cat $1 2>/dev/null ;; # *) FILE=`file -L $1` ; # Check to see if binary, if so -- view with 'strings' # FILE1=`echo $FILE | cut -d ' ' -f 2` # FILE2=`echo $FILE | cut -d ' ' -f 3` # if [ "$FILE1" = "Linux/i386" -o "$FILE2" = "Linux/i386" \ # -o "$FILE1" = "ELF" -o "$FILE2" = "ELF" ]; then # strings $1 # fi ;; esac
