list all instances of a file in your PATH directories (without duplicates) in PATH order

The wherepath function will search all the directories in your PATH and print a unique list of locations in the order they are first found in the PATH. (PATH often has redundant entries.) It will automatically use your 'ls' alias if you have one or you can hardcode your favorite 'ls' options in the function to get a long listing or color output for example. Alternatives: 'whereis' only searches certain fixed locations. 'which -a' searches all the directories in your path but prints duplicates. 'locate' is great but isn't installed everywhere (and it's often too verbose). Show Sample Output

Find all files over a set size and displays accordingly

This is an updated version that some one provided me via another "find" command to find files over a certain size. Keep in mind you may have to mess around with the print values depending on your system to get the correct output you want. This was tested on FC and Cent based servers.

A way to run commands on a remote computer to be displayed on the remote computer

This is a simple solution to running a remote program on a remote computer on the remote display through ssh. 1. Create an empty 'commander' file in the directory where you intend on running these commands. 2. Run the command 3. Hop on another computer and ssh in to the PC where you ran the command 4. cd to the directory where the 'commander' file is. 5. Test it by doing the following: echo "xeyes" > commander 6. If it worked properly, then xeyes will popup on the remote computer. Combined with my other one liner, you can place those in some start-up scripts and be able to screw with your wife/daughter/siblings, w/e by either launching programs or sending notifications(my other one liner). Also, creates a log file named comm_log in working directory that logs all commands ran.

How to delete all the archive files with extension *.tar.gz and greater than 10MB?

give record size of given record-structured file

command was too long... this is the complete command: fname=$1; f=$( ls -la $fname ); if [ -n "$f" ]; then fsz=$( echo $f | awk '{ print $5 }' ); if [ "$fsz" -ne "0" ]; then nrrec=$( wc -l $fname | awk '{ print $1 }' ); recsz=$( expr $fsz / $nrrec ); echo "$recsz"; else echo "0"; fi else echo "file $fname does not exist" >&2; fi First the input is stored in var $fname The file is checked for existance using "ls -lart". If the output of "ls -lart" is empty, the error message is given on stderr Otherwise the filelength is taken from the output of "ls -lart" (5th field) With "wc -l" the number of records (or lines) is taken. The record size is filelength devided by the number of records. please note: this method does not take into account any headers, variable length records and only works on ascii files where the records are sperated by 0x0A (or 0x0A/0x0D on MS-DOS/Windows). Show Sample Output

0 if the file is 0-length

List only those files that has all uppercase letters in their names (e.g. README)

Some source package have many 'README' kind of files, among many other regular files/directories. This command could be useful when one wants to list only 'README' kind of files among jungle of other files. (e.g. I came across this situation after downloading source for module-init-tools) Warning: This command would miss a file like => README.1 (or one with spaces in-between) Corrections welcome.

number files in directory according to their modification time

i use this after ripping internet radio streams to number the files as they originally played (even though streamripper can do this with -q). to number other types of files, or all files, just change the *mp3. to rename directories only you could use ... ls -lt | grep ^d | cut -d ":" -f2 | cut -d " " -f2- | while read ...

shell equivalent of a boss button

Nobody wants the boss to notice when you're slacking off. This will fill your shell with random data, parts of it highlighted. Note that 'highlight' is the Perl module App::highlight, not "a universal sourcecode to formatted text converter." You'll also need Term::ANSIColor.
