I have a file containing many lines, and I want to display only the first word of each line with the Linux commands.
How can I do that?

To print a whole word, you want -f 1 , not -c 1 . And since the default field delimiter is TAB rather than SPACE, you need to use the -d option.
The ^ character is what instructs the sed command to add a character to the beginning of each line. Here's the syntax for adding a space to the beginning of each line using sed . Alternatively, use the -i option with the sed command to edit a file in place.
To look at the first few lines of a file, type head filename, where filename is the name of the file you want to look at, and then press <Enter>. By default, head shows you the first 10 lines of a file.
Try doing this using grep :
grep -Eo '^[^ ]+' file If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
