Should do exactly the same - compress every file in the current directory. You can even use it recursively:
gzip -r .-3gzip * -
While it seems (to me at least) a little counter-intuitive to filter on name first, this requires less work for find, as it allows it to immediately discount any files that do not match the name directly from the directory listing on disk. Querying against file attributes requires reading the file attributes, which is performed for all files matching any name based predicates. Show Sample Output
1find ${PATH//:/ } -iname "*admin*" -executable -type f -
Compresses each file individually, creating a $fileneame.tar.gz and removes the uncompressed version, usefull if you have lots of files and don't want 1 huge archive containing them all. you could replace ls with ls *.pdf to just perform the action on pdfs for example.
-2ls | while read filename; do tar -czvf "$filename".tar.gz "$filename"; rm "$filename"; done -

Prints a log of phonecalls placed from/to an asterisk server, formated into an easily readable table. You can use partial number/queue matches, or use .* to match everything. Show Sample Output
3phonelogs() { grep "$1" /var/log/asterisk/cdr-csv/Master.csv | cut -d',' -f 2,3,11,12 --output-delimiter=" " | sed 's/"//g' | cut -d' ' -f 1,2,3,4,6 | column -t; } -
Gets the IP addresses of all interfaces except loopback. Cuts out all of the extra text. Shorter than the other options, and much easier to type. 'ifconfig | grep cast' is enough to get the IP address, but it doesn't strip the rest of the junk out. Show Sample Output
0ifconfig | grep cast | cut -d':' -f2 | cut -d' ' -f1 -

1sed -i.backup '/patter/{n;s/foo/bar/g}' file
-
Prints the top 10 memory consuming processes (with children and instances aggregated) sorted by total RSS and calculates the percentage of total RAM each uses. Please note that since RSS can include shared libraries it is possible for the percentages to add up to more that the total amount of RAM, but this still gives you a pretty good idea. Also note that this does not work with the mawk version of awk, but it works fine with GNU Awk which is on most Linux systems. It also does not work on OS X. Show Sample Output
3TR=`free|grep Mem:|awk '{print $2}'`;ps axo rss,comm,pid|awk -v tr=$TR '{proc_list[$2]+=$1;} END {for (proc in proc_list) {proc_pct=(proc_list[proc]/tr)*100; printf("%d\t%-16s\t%0.2f%\n",proc_list[proc],proc,proc_pct);}}'|sort -n |tail -n 10 -

Use color escape sequences and sed to colorize the output of svn stat -u.

Show active calls as the happen on an Asterisk server. Note that the Asterisk command (in single quotes) is formatted for Asterisk 1.6. Use the -n flag on the watch command to modify the refresh period (in seconds - default is 2 seconds). Show Sample Output

While editing a source file in vim, or using vimdiff to compare two or more files, the ':TOhtml' command can be used to export each buffer as an html file, including syntax highlighting and vimdiff colorization.

dushfor the above output,dush -n 3for only the 3 biggest files and so on. It's always a good idea to have this line in your .profile or .bashrc Show Sample Output29alias dush="du -sm *|sort -n|tail" -
