Open your favorite editor and create a script as below,
[bash] #!/bin/sh #get the name of file to check if its present or not in pwd FILE_TO_CHECK=$1 if [ ! -f $FILE_TO_CHECK ] then echo "file $FILE_TO_CHECK does not exits" else echo "file $FILE_TO_CHECK is present" fi [/bash]Now, lets say you want to search myfile.pdf in a big list of files in a directory, then cd to that directory, copy this script there, and run the script as,
$ bash script_to_check_file.sh myfile.pdf
