ls [target path] : list contents of target area. The output of the cmd can be piped into other system cmd. eg ls <path> | grep txt
cd <target directory> : To change the current directory within the sretrive shell.
pwd : Prints the full pathname of the current directory within the sretrive shell.
get <file or directory path> : download directory/files into the directory where sretrieve shell cmd was invoked
less <file path> : Read input file to allows backward movement in the file as well as forward movement
cat <file path> : show the contents of a file. The output of the cmd can be piped into other system cmd.
sgrep <search path> <pattern> [options] : Similar to unix grep cmd But with diffrent parameter ordering. The output of the cmd can be piped into other system cmd.
