I have this assignment
The FILE variable is the name of a text file that contains exactly 30 lines. Each line consists of just one word, consisting of uppercase and lowercase letters and numbers.
Change this file so that all digits disappear from the words, all letters change to lowercase, and the modified words are sorted alphabetically in ascending order. The modified file will have the format of three columns of separate tables, where the first column will contain the first 10 words after sorting, the second column the second 10 and the rest the third. Number the lines of the file.

I created this script, it works for me, but not on the school server. You don't know where the problem might be. Thank you
cat $FILE | tr '[:upper:]' '[:lower:]' | tr -d "[0-9]" | sort >file1.txt;
split -l 10 file1.txt; paste xaa xab xac >file2.txt; nl file2.txt;
Stderr mismatch:

/home/blxrpcdcgb/Student: line 1: $FILE: ambiguous redirect
paste: xaa: No such file or directory
------------------
'"$HOME"/file1.txt' is excessive.
'"$HOME"/file2.txt' is excessive.
'"$HOME"/kfekd jojny' has incorrect content:

You can use pr for arranging the columns. No intermediate files are needed:
tr [:upper:] [:lower:] < "${FILE}" \
| tr -d [:digit:] \
| sort \
| pr -t3 \
| nl
or in one line:
tr [:upper:] [:lower:] < "${FILE}" | tr -d [:digit:] | sort | pr -t3 | nl
