More details about the dos2unix command (man page) Another way to tell if your file is in dos/Win format: cat scriptname.sh | sed 's/\r/

Join them; it only command not takes a minute: Sign up command not found error in bash script up vote 3 down vote favorite I have written a bash script. It basicaly gets three paths based on input parameters and then then gets the imagename/filename in the path. Something like: I provide: AA=/home/user Then it uses the find command to get /home/user/dir2/images/dir/tellmeimage1fun.bin Finally I have to get command not found tellmeimage1fun.bin as output. Script: #!/bin/bash echo "arg0 n/k/d" AA=$1 CC=$3 PATH1="`find $AA/dir2/images/dir/ -name *image1*.bin`" PATH2="`find $AA/dir2/images/dir/ -name *bimage2*.bin`" PATH3="`find $AA/dir2/images/dir/ -name *cimage3*.bin`" if [ $CC = "n" ] ; then PATH=$PATH1 elif [ $CC = "k" ] ; then PATH=$PATH2 else PATH=$PATH3 fi #Getting filename name from path: IMG="`ls $PATH | cut -d "/" -f6`" OUTPUT: /users/prasapat/bin/sl5: line 22: ls: command not found /users/prasapat/bin/sl5: line 22: cut: command not found If I give complete paths to ls and cut they work. But i dont want to do that for all commands in the script. If i remove the last line and echo the PATH variable it is completely fine. Only after adding the last command, I see the probelm. Kindly help and let me know if I have done any obvious error. bash share|improve this question edited Apr 12 '11 at 22:54 John Flatness 19.2k25468 asked Apr 12 '11 at 22:48 Pkp 33941226 add a comment| 5 Answers 5 active oldest votes up vote 7 down vote accepted The problem is that you are redefining the PATH variable where ba
FreeBSD, Linux, UNIXWhy I am getting the error Command not found? How do I fix this problem? A common question asked by new Linux or UNIX users. When you get the error "Command not found" it means that Linux or UNIX searched for command everywhere it knew to look and could not find a program by that name. Another cause is you misspelled the command name (typo) or administrator does not at all install the command on your Linux/UNIX based system. To get rid of this error try the following suggestions:
Make sure command was not misspelledAll Linux and UNIX commands are case sensitive and you need to type correct spelling of command.Make sure command is your pathYou can see current search path with following command:$ echo $PATHSample outputs:/usr/bin:/bin:/usr/sbin:/sbin:/usr/X11R6/bin:/usr/local/bin:/home/vivekgite/binUsually, all user commands are in /bin and /usr/bin or /usr/local/bin directories. All your programs are installed in these directories. When you type the clear command, you are running /usr/bin/clear. So if it is not in your path try to add directories to your search path as follows (setup Linux or UNIX search path with following bash export command):$ export PATH=$PATH:/bin:/usr/local/binYou can also find out of path of any command with which or whereis commands:$ which ls/bin/ls$ which gcc/usr/bin/gcc$ which date/bin/date$ which cal/usr/bin/cal$ whereis gcc/usr/bin/gccYou can run a program using its full pathname as follows:$ /bin/ls $ /bin/dateFinally, sometime you may not have permission to run the command.ExampleLet's assume the program you want to execute is called "cal" and you get a "Command not found" message from Unix or Linux. First, type the following command to see if you get a path name: $ whereis cal Sample outputs:cal: /usr/bin/cal /usr/share/man/man1/cal.1.gzIf you do, you can invoke it using a full path name (e.g. /usr/bin/cal): $ /usr/bin/cal Sample outputs: September 2012 Su Mo Tu We Th Fr Sa 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 Or You can add the path to your PATH variable in your shell start-up file $HOME/.cshrc (csh/tcsh) or $HOME/.bashrc (bash) file, then "source" the file: $ vi $HOME/.bashrc Add the path as follows: PATH=$PATH:/home/vivek/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games export PATH Save and close the file. Run the following command: $ source ~/.bashrc$ echo $PATH
$ cal Finally, you can use the following command to search for cal command get a hit about its location. $ find / -name cal -print Then, invoke it using a full path name or add it to your PATH variable in your shell startup file. Share this tutor
