sed basic replacement

sed -i 's/old/new/g' filename

if you issue the above command, it will modify the word "old" with "new" word (where ever the old word appear - globally (g))

sed man page
Man Page for sed (OpenSolaris Section 1) - The UNIX and Linux Forums

For this question, we need to introduce a regular expression (in the place of old ) to remove the characters upto =

Code:
 
bash-3.00$ !sed
sed -n 's/^.*=\(.\)/\1/p' test
1
2
3
214
bash-3.00$ cat test
aasaasas=1
bsasasasasa=2
sawqas=3
abc=214

your command gives the correct ouput.

Code:
 
bash-3.00$ sed 's/.*=//' test
1
2
3
214
