Question

From the line

/mnt/sampleserver/test_1/myfile.pdf

Please suggest me how to do it using linux commands.

Answer 1

Use the 'basename' command. Something like this: basename /mnt/sampleserver/test_1/myfile.pdf

You can use any text processing tool, for example, sed:

% echo "/mnt/sampleserver/test_1/myfile.pdf" | sed -e 's|/mnt/sampleserver/test_1/||'
myfile.pdf

Answer 3

Several ways:

file="/mnt/sampleserver/test_1/myfile.pdf"

$ echo ${file##*/}
myfile.pdf

$ echo $file | cut -d/ -f5
myfile.pdf

$ echo $file | awk -F/ '{print $5}'
myfile.pdf

Answer 4

Following should get you going. (Note the "\\" for escape character)

/bin/sed -i "s//mnt/sampleserver/test_1///"
